INDY 572-13 HEADS ? - 07/09/12 04:46 AM

Who has a good price and are good at making them make horse power over my set of 440-1s i am going to get a set a little later i would like to keep my motor the same just change the heads my 440-1s are out of the box they have no port work on them do you all think 572-13s will make 50 to 100 more HP over my 440-1s THANKS for any help .

I think with 572s i can still use my intake and tray and pistons?

It would be cheaper to port the -1's

Do you think they will make 50 to 100 more HP then what they are making now ?

Not sure about hp numbers, but I think that a ported -1 would out flow an ootb 572-13..

Check these ported numbers.. The 572-13 barely out flows the -1's both ported..

Check Modern and Porter to compare.. I believe they're both about 375 @ .700 lift..

Like I said, I would just port the -1's.. On a 572" with stock 440-1's, you are giving up quite a bit of power. So 50-100hp I would guess is possible.

IMO dont waste your money on the -13 head. Not worth the expense, better options ou tthere for sure. As Chris said porting what oyu have and getting a cam to match that will save you money and likely gain you a good deal of HP as well.

You need a 4.5 bore for the 572's and different pistons. I made the switch to them. Modern did my set. Had these done at the begining of last year. Just got the motor together so no results yet. Here is the flow sheet.

Re: INDY 572-13 HEADS ? - 07/09/12 10:23 AM

If you have no porting, the motor should pick up a solid 100 hp on a race motor with 572 cubes. I am making about 900 hp, or enough to go consistent 8.80s with 3050 lbs car and driver. You should be able to match that power level with a full port job. After that it will get expensive, because the 572 needs new pistons, and at that point you might as well sell what you have and step up to a B1 head. A B1Mc will make over 1,000 hp, ask Al for details.

As mentioned, you'll be better off porting the heads you've got. Personally I wouldn't upgrade from -1's to -13's I'd go for at least B1-MC's.
Again this has been mentioned but, you will need new pistons as the valve reliefs are bigger and in a different place, also I'm not sure if the headers will swop over either, the -13's are cut back some along the exhaust side face. Also you would be better off going to the 3X intake as the others don't seem to have a lot of material to match the roof of the intake port. For the gains I'm not sure it's worth it.
If and when I get round to upgrading, B1-PSO's will be on the top of the list.

I have a set of tti 2 1/8 step headers bolted to my motor now fit the same as the 2 inch I had on the -1's. I too would just port out the -1's If I were him. Only reason I upgraded to these was it was the biggest head I could fit under the stock heed with no scoop and use off the shelf headers. Modern cut the exhaust exits the same as the -1's not like indy does so I could use the headers I wanted. I would have gone with a b-1 head but it would not have cleared my factory hood.

TTM thanks for the info! always wonder that about going 572's! real curious how your new 572s will work for your car and real curious on your pickup going to those heads... keep us updated on that so we can see value of upgrading to those heads

Re: INDY 572-13 HEADS ? - 07/09/12 03:59 PM

As other's have mentioned, the piston valve reliefs are different for 572-13 heads. 13 degree vs 15 degree, moved location.

For the real step-up, the B1 originals would be my choice. But if you have fairly new 440-1 heads, and you said no porting, there may be room for much improved porting to around 375 cfm with the 2.25" intake valve. I don't know if your current port shape would interfere with the current CNC porting programs for 440-1 heads. OOTB 440-1 don't flow well at all, so a CNC would be a big improvement, IMO.

You will need to check your piston valve reliefs if you change to the 440-1 2.25" intake valve. Some are OK, some are not.

Holy Crap,I spent my hard earned $$$ buying not just 1 set but 2 sets of 572-13 heads,when I could have save $$$ by using 440-1 heads

I just let 1 set go with my spare engine,but you can bet the farm on this I won't be replacing them with a set of 440-1 heads.

Posted By: Slingshot383

Re: INDY 572-13 HEADS ? - 07/09/12 05:17 PM

The B-1's are far from a bolt on set of heads, they are a lot more work to get a total package assembled than the switch to the 572-13's.

Re: INDY 572-13 HEADS ? - 07/09/12 05:26 PM

Port work and a good cam will easily get you another 100 or so over OOTB -1 heads. You can crack 900 or so with a 572 with -1 heads and the right cam and components/

that is so true. the 572-13,s have alot more port volume than the -1,s, at the same flow.....

You got that right. So lets start the list of 1000+ hp -13 motors out there

I do know of one but it is a BIG motor...

It is your money spend it however you like but IMO there are better valuaes out there than the 572-13 head for the money. As for the OP seems the consensus is to save money and port what you have. If you want to upgrade I think most will agree DONT go to the -13. But we are all likely wrong

When I can afford to upgrade I'll likely chose the B1 PSO's.
The -13's have a place, They don't have the complexity / valve train issues of the B1's.
If you are after max HP then the Hemi head is the choice.

I see there is still a few smart people out there!

add mine to that 1,000 hp list(mine has 572-13 heads),if not that or more how does it run the ET it runs?

You can argue flow sheets & dyno numbers and it is nothing more than Gossip,when you put it in the car and it runs the numbers that's what counts!
I have been doing this a good while now and believe me as much $$$ as I put into engines over the years if I could or knew of anyone that could make more Horse-Power with a B1 engine and back those numbers up in the car I would have a B1 engine instead of a Indy engine.

I'm not loyal to Indy,as much $$$ as I have spent on Indy products I do not get any favors from them. I never bash B1 heads or any of the other people that build Mopar parts,in fact I wish we had more companies building good Mopar race parts like the X brand racers have.
Right now if you want a Mopar Race engine you either buy Indy they sell the blocks and everything else or B1 Heads and everything else from another supplier.They charge us what ever price they want,and if we want to go fast we have to buy it from one or the other of them and they both know it.

It seems out here on the East coast we only know how to make the Indy engines run fast.Our Indy engines make Big horse power @ 7400-7600 RPM!
Where as out on the West coast the B1 engines is the only engine you all out there know how to make run fast.What RPM do you guys how to turn those B1 engines to make Big horse power? is it in the high 8000-low 9000 RPM

the predator head guys could say the same thing about b-1,s. " dont waste your money on b-1,s, when you know predator,s out perform them"

On my first post I attached a flow sheet from modern on a 4.5 bore. Only reason I say for him to port the heads he has is it would cost him the least amount of money. Now if he wanted a Cnc port job and wanted the most flow he would be better off getting new heads as indy makes casting dedicated just for cnc program for the bigger port volumes. I went with t&d rockers on my -13's they oil through the pushrods as I did not want spray bar oiling like you need with jessel rockers. I was pretty happy with the flow numbers from the heads.

Billy,
Your dragster runs fast for sure. Other than yours, and I'd still like to know what it weighs, I haven't seen a 572-13 motor that was worth the switch when you could upgrade to the B1 for the same money again JMO.
B1 problems with rocker geometry is something I don't know anything about, and I've owned 3 different 572 B1's that run 7.30's at 183, and that's in a 1850# car with a wing at Las Vegas. It runs that ET and MPH at around 7500RPM, shifting at 7200-7300. Also, the Koffels are much easier to deal with IMO.

Re: INDY 572-13 HEADS ? - 07/09/12 09:41 PM

For the OP,

Like others have stated, if you are just looking to make 50-100 more HP, porting your -1's will be best bet and cheaper in the long run. Your current heads placed in the "right" hands will make the HP range you are looking for. Probably need a cam change too, maybe.

What kills me is all this talk of -13's won't run. I'm sure there are plenty of them on motors running real good; its not fair to say they won't run just because many, many other racers don't frequent this forum to share their story on the performance of their motor w/-13's.

Lets not FORGET, a former Best Machine customer (Lane Lambert) in a somewhat heavy Dart set some All-Motor classes on their ASS with a set of well prepared -13's and 581" Wedge. He did it in competition with a 1.28 60', 8.55 @ 159 in Toronto @ #3310 on a small tire......and it was not a 1-run wonder; car ran fast all the time and won multiple races, 6-yrs ago!!!!!!!! Lane and BMRE went separate ways, but that hotrod was fast!

As far as people stating B1's having valve train issues, this or that......yeah they probably do when placed in the "wrong" hands or people just throwing them together in a hurry......it ain't the heads that have problems......lol.

Haven't made up my mind yet, but I have 572-13's w/Jesel indiv. shaft rockers on my motor currently, but I am seriously considering selling them; they have been CNC'd by Jeff at MCH w/flow data. If I sell I'm going B1-PSO or Predator top-half. Just have not figured out what direction to go yet. IF I make a change, Brian at IMM will get the call for the work.

when i had my cnc 365cc flowed they did:
.100 68
.200 124
.300 174
.400 236.4
.500 306.6
.600 357.2
.700 376.5
.800 388

4.5"bore
28" h2o

i would think the 385cc would do better.....

No, that is my friend Rob. Bought the car from him a while back and made some changes/upgrades to it since then. I used to own the tan 540 B1 '72 Dart that I sold to Steve; owner of Predator Perf.

Al, I don't want you to surrender,that would be no fun.

I was only talking to you on the add my engine to your 1,000 hp list. As for how fast your little B1 engine would be in a 1450 lb dragster,not very fast at all

you would be lucky to make it to the 60' time clocks,ask me how I know.Be fore warned I am building a new engine that will out Horse-Power you Hemi engine even on the dyno.

The heads(your Big O'll Hemi heads) will even be up to par if not better than your heads on a flow beach.

I enjoy these head topics or should I call them Head Games.

For a couple of weeks everyone will say run the SR heads,them Big O'll 440-1 heads are just too much you don't need that much head.

Then in a week or two the same ones will be saying,them 440-1 heads won't flow enough not even the 572-13 heads.Indy doesn't make a head big enough to make a 1,000 hp with.
The only thing I enjoy more than reading post like these,is all of you here on Moparts.Because most of you have came through with advice & help when I needed it.

Now I will try and help steeldust...In my opinion I think the 572-13 heads would be your best choice.They will work fine now and even better if at a later date if you decide to up the cu in.

So for about $1500 or so you can port the 440-1's and get what you need or spend $4000-5000 and get more than you need..

Well unless your willing to change pistons, and since you just want a tenth more I would just send your current 440-1 offs the get ported and fresh valve job.

Well to answer the original question 440-1 great head but of course the 13's make more power.Who has the best price on the 440-1's I dont know but look at who is an Indy dealer on here, try Performance Only,Competionwedge or Bob George.

Congrats Billy

on getting your dragster to 1450 as I just bought an altered that weighs 200 lbs more than you with a small block Guess Iam an idiot

Just a few short years ago, we as Mopar enthusiasts, racers and builders couldnt even debate a topic like this! Now look at it, we have so many choices, we cant decide...

I got my INDY 440-1 heads from Mancini Racing they are real helpful and they know MOPARS. I guess i see about getting my heads ported .

If you noticed I am not the one that said it weights 1450 lbs

That was AL

But it is a light car and if you have a steel block SB,my all aluminum Indy engine will be just as light as yours Indy says they weigh 475 lbs complete with tunnel ram and 2 1150 Holley's mime has 2 1475 Terminators. I would guess with me in it 1700-1750 lbs,I would be very surprised if it is 1800 lbs.I spent a lot of $$$ trying to keep mine light. I may be wrong but I think you will find that most altered's are as heavy if not heavier than a dragster.

steeldust,another thing to consider is with the heat we are having it may be better to have a little more power than needed.If things keep going(weather wise)at the rate they are going now toward the end of this month and the next couple of months you may need to be holding back a full tenth.

Dwayne posted some Indy flow numbers with various levels of machining. Nice improvement in the -1's with minimal work

https://board.moparts.org/ubbthreads/show...rue#Post7043642

Dwayne prepped the ICH 295 EZ's on my pump gas 572 (that he built) and it made 720hp/725tq. I'm sure he could do just as good or better with a set of -1's

Re: INDY 572-13 HEADS ? - 07/10/12 05:58 AM

Yeah what he said!!!!
There are several -13 heads making at or near a grand. We have been involved with several in everything from pulling trucks to mud racers. I am just saying to the original poster. If that is all you need or want there are easier and less expensive ways to do it.

Re: INDY 572-13 HEADS ? - 07/10/12 05:15 PM

Is all this talk just with running a single 4 bbl. carb.? What about tunnel rams an a pair of Dominators, or fuel injection? Bet the answer on heads changes a little then.

Posted By: Al_Alguire

Re: INDY 572-13 HEADS ? - 07/10/12 06:21 PM

Well my junk is single 4, cast intake that is unported.

I am sure the experts will tell you that my on track numbers dont bear out the dyno numbers. 2875lbs 8.0's at 169 and change from 525" of B1. With the stop on it set up for S/ST, with that convertor we have been 8.teens at 165. Would love to hear what the experts think it should run with a dynoed 1050hp.

FWIW 1000hp in a 1750lb dragster

should be able to go 7.0's at close to 190

Posted By: MRMOPAR622

Re: INDY 572-13 HEADS ? - 07/10/12 09:34 PM

Mine will do that Al,and more in T/D trim.

But don't think I just stuck the big engine in it and it started running those numbers.

I have the tunnel-ram and 2 1475 Terminators on mine. I think the Terminators and alcohol play a big part in my cars performance along with the torque converter.

PS I don't see the Big engines getting enough fuel with 1 carb.

Just to help out the experts a buddy of mine running 1025 hp went 8.00s at 2550 lbs, so looken pretty good there Al

I guess you know a thing or two about 572-13 heads you run them do you think by putting 572s on will they make that big of a difference over my 440-1s or if i get my heads ported would the 572s still make a difference

when i do this i won`t to do it right or i hope are the 572s that good of a head thanks

Re: INDY 572-13 HEADS ? - 07/14/12 02:39 PM

If it was me I would go with the 572-13 heads.I have found its best to go ahead and get the best you can at the start,because even if the 440-1 heads do what you want at the start you will soon be wishing you had gone with the 572-13 heads.I have never wish I had built a small engine.With the 572-13 heads you will also have enough heads to go with more cu in later if you should chose to do so.
I have been very Happy with my 572-13 heads,never once have wish I had gone with the 440-1's.

Re: INDY 572-13 HEADS ? - 07/16/12 01:16 PM

Just an observation on what each head you may consider will do. The 440-1, then 572-13, then B1, and finally the B1Mc.
The performance level goes up close to the same as you move up to each head. Although I think the 572-13 isn't too far behind the B1, The 440-1 will make about 850 on most builds, 572 another 50 hp, and so on. The B1mc has shown itself to make over 1050 with the right parts. So its a matter of cost Vs dollars, or if you really like on head style over the other, and you seem to want to stay with the Indys, fine. The 572 has different valve angles, 13 vs 15, and moved valve location which requires a different piston. I don't know if it is possible to cut the new notches in your old pistons, but may be worth investigating. The Rocker assembly's are different if you run Jesel. If the bars that bolt to the heads are the same, you may be able to purchase just part of the setup (exhaust rockers?) and save some $$.

Greg thanks i have spent a lot of money on my car and my motor and would like to freshen it up over the winter and get it to run at about tenth or a little more and keep the short block the same if i can but i don`t won`t to spend money on my heads if they won`t do it i could get a set of 345 cnc bare heads and put some of my stuff in them that`s what brad was talking to me about to save some money i just think 572s will make the power with a 572 cui motor because when it`s cool and the air good i can go 5.90s now but when the air is at about 3,400 to 4,400 ft and real hot and the track is slick i need about a tenth and i have had a lot of helpful talk
