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. 
I would run another set of -13's anyday, It's not all about flow numbers. 
 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 would run another set of -13's anyday, It's not all about flow numbers. that is so true. the 572-13,s have alot more port volume than the -1,s, at the same flow I see there is still a few smart people out there! Al 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"

Anyone have flow numbers on the -13 385cc with a 4.5inch bore? Quote:
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.

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

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

[Re: EvilB1Dart] #7284697 - Mon Jul 09 2012 04:55 PM Reply to this post Reply Reply to this post Quote Billy I surrender, I know you love bustin my ball$..I know my 2900lb little B1 running 8.0's at 170 is not worthy in your eye nor a match for that all mighty Indy motor in your little dragster for sure. I will crawl back in my hole and just be in awe Wonder how fast my little B1 would be in a 1450lb dragster anyway 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.

I am looking for a tenth or a little more the car will run 5.90s in good cool air but i need 6.00 to 6.02 in real bad hot air and a slick track it run 6.05 & 6.04 & 6.04 & 6.06 & 6.04 and i lost with a 6.04 and the air was hot and bad that`s why i was asking about the 572-13s .
It's your money..
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..
