Any problems with Indy hemi heads ? - 03/10/09 09:57 PM

going to buy a set of indy hemi aluminum heads this week that were cnc ported from indy to 450 cfm.
a fellow moparts member stated to me today that there was a problem with them and something had to be fixed or corrected in order for them not to
mess up my motor when installed. is this true or are there any issues with them?
anyone have any feedback on the indy 426 crossram?
thanks

Chris,450 cfm at what lift?What is the problem with them?As you know we run Indys on our 528",588" and 605" without any problems for quite a few years.

You may be surprised or should I say disappointed with them.

I wouldn't say that, but they are taller and wider than MP heads by a bunch. I had to center the engine better, and relocate it somewhat to clear eveything. They are 1.5" wider at their widest point, and at least 3/4" taller with vavlve covers.

Which heads did you get the 426-1's? And did you get one of Indy's cross rams?

THATS what im trying to figure out, fore warned is fore armed!
are these a straight bolt on?
for 1:6 indy rockers, do the indy heads need to be clearanced for pushrod movement.like the mp heads

I have a set of Indy's CNC ported Hemi heads and had no issues with running them BUT I did find out that during an inspection of the heads and springs, I found that the spring heights were all off, the springs were not sized properly for the cam, and obvioulsy set up by someone who didn't care or know what they were doing. The springs were assembled using the same shim under every spring and installation heights were not corrected. There was about .050 varience in spring height from biggest to smallest. I bought a tool to machine the spring pocket to accept a spring cup and corrected the depth at the same time.
Oh, did I mention I bought these new and direct from Indy ... You would think they would know better...

chris get it in writing that they will replace your existing heads with out interference! russ and kenny stuck it where the sun don't shine on me and i will never forget it!!!! i had been told previously that the indy hemi heads needed a different dome configuration than a standard hemi dome i called to confirm this and spoke with kenny at least a half hour about the install on these heads . ken assured me they were a direcr replacement for stocker heads. well as hemi itis and others have seen they were not ! not only were the combustion chambers not the same radius as a stock head they were not even in proper bore spacing config. being confident after spending $9000.00 plus dollars with indy cylinder junk!!! and feeling i was being told the truth i just installed them checked piston to valve and went to the track to test for the pump gas drags two years ago, well 4 passes and a trip down the street and expired hemi it was ! broken rods broken block hurt crank damaged heads bent camshaft etc. the worst of it all a broken heart over this situation. i dissasembled the engine to find out the combustion chambers were .050 narrower front to rear thanmy stock heads making them oval shaped instead of round i even set up in my bridge port with my ball mill for machining the hemi combustion chambers on oem heads and the indys are not even close.
so i called to complain and got the master of all ceramonies russ , i got to tell you i might have gotten a little soft the last few years but i will never for get what he said "yhea what do you want me to do about" . he better hope i dont find him in a dark alley because he is in trouble!
in reality i did not do my checks like i should have because i trusted someone else, and growing up in a hemi s/s family i know better, i still feel after the money i spent there could have been some kind better customer/business response. i will never use indy for anything again i would build a pontiac with chevy heads and a ford car before i would call indy for anything.

i hope this helps your decision, call stage five!!!!

p.s. how much fuel do you have?

Be careful that your pistons fit the Indy head chamber.When ordering pistons we always specify for Indy head chamber. I would ask for the flow sheet for those heads and the chamber size and volume.Still wandering 450 cfm at what lift?

Bob can you explain why we continue to see inferior work coming out of indy? seems like some body would make an effort to send things out that are right

98% of the people on this board have said the Indy stuff needs to be purchased through a 3rd party that will look over and clen up the stuff. Even Chris complained about Indy in the past but he is still willing to go direct through Indy get the Indy products through any WD and have them look them over and make them correct and you will have a great product

thats no excuse imo. they have a complete machine shop, nothing should have to be sent anywhere when it leaves. not everybody reads all the posts on moparts.

Tony,I can't really answer that.I use them as a supplier,my engine programs are all developed around Indy blocks and heads.That we as engine builders go over most everything we use in a build insures that the product is correct is what everyone should do.To rely on the manufacture to build things to our specification would limit us to changes during the build.I'am very satisfied with the products and their CNC programs as well as their handling of our account.The staff have be very helful in resolving any issues that arise.As far as Russ and Kenny,they are very helpful and we very seldom bother them for every little problem,but when necessary they are always helpful.We make sure that our customers are satisfied since they rely on BGR for their needs.To be honest we have not had any complaints from customers that we drop ship direct from Indy to.No matter who the manufacture or supplier is the builder or end user must check everything.We are in the processing of correcting for use multipal sets of Jesel and T/D rockers as well as a lot of valve train componants that don't work or fit properly.Follow all the other post about Strange,Barry Grant,Comp Cams,Harland Sharp,440 Source and on and on.Seems no ones perfect.We do the best we can with what we have.When things are produced on a large scale anything can happen.I have no quick answer for anyone.

Oh, I'm sorry I forgot. You live in a perfect world while the rest of us don't. Who here also posted about the expensive Impact products? I guess all companies have people working for them and we know all people are not perfect and mistakes will be made - unless they are from Florida, everything down there is perfect!

I am glad I read this post. I bought a set of the indy 426-1 heads at the swap meet this weekend and the rocker arm hold downs. I am now debating how many cubic inches to make the motor and I was not aware that the Indy heads took a different piston. Where is the best place to get the pistons? I looked at buying a set from moore and moore at indy this weekend, but didnt. I guess I am glad I didnt since theres were the mopar wiesco pistons.

Specify that you are using Indy heads to the piston mfg or supplier.Chris can purchase his heads from whomever he wants,just make sure they are correct for his application and combo. Life is not what you expect sometimes,ever go out with a beautiful girl only to find she's a guy?Surprise!!!Life is like a box of chocolates,you never know what your going to get.

that is exactly my point! i specified cp hemi pistons to kenny and he said absolutly no problems with fit! now i know the difference and you already know it. i got lied to and two years later i still frustrated.

Jimi,We had the same problem years ago with a set of pistons we got from Chrysler,they smacked the heads front to back.They beat off the chamber and grenaded the engine in the lights at 142mph.It's not something you soon forget.

i cut every set of indy heads i port back to the std hemi dome/chamber radius. i was amazed it wasnt a std hemi radius, i never asked russ why he changed it,, or if he knew.

I wonder if that's something new? I never had that problem with mine, but I bought probably the 6th set they ever made when they came out. Mines 11.6:1 with JE pistons, and never had that problem.

How can I measure one for this issue? I have them off the car currently.

Bob thats not what I am talking about. doing a correct vavle job is not making them to a customers specs. quality control is the issue, hjere's my feelings for what it's worth. I have used many indy parts and like them. here's the but, if they are going to sell them they should tell people they are rough and need to be sent to a machine shop for correction. not every body knows to have BG or somebody else build them and make sure everything is correct. and thinking they are buying them directly from indy thinking they are right. if it were me I would have quality machine help and quality control to make sure nothing went out thats wasn't dead on. just a matter of pride to me, guess they don't have any..

Russ, trust me, i wont ever buy direct from them again. i am going to get them from a indy dealer.
ARC built my hemi motor and it made great power so i will continue to let him build my motors and clearance all the parts for me. he is more than capable in checking the parts prior to assembly.

DRAGULA i also have 11.6 compression with JE pistons, im hoping there wont be any more machine work involved.
was wondering if the pistons will need to get flycut.

Well anything that is mass produced is going to have what I call Go-No Go set of tolerances..
If you want it exact as possible that means CC each chamber, muli cut valve job and milling along with port matching...On our motors I usally get un-cut domes so I can fit domes to heads and flycut my own valve reliefs..Indy stuff has made it possible for Mopar racers to have some good componets to build with, instead of having to find 40 year old stuff to build motors with.

Re: Any problems with Indy hemi heads ? - 03/12/09 03:31 AM

FWIW: I have used Indy heads when the customer specifically asks for them - otherwise I use Stage-V. But I have noticed that sometimes the Indy Hemi chambers are fine (meaning I didn't need a special piston) and other times I have seen them tight in one axis or another. For a street Hemi either would have worked, but as you start pushing the CR the dome fit becomes critical. Since then I always use clay to not only check for P-to-V, but I also put some clay around the outside so I can check for the "Squench". Once I found that the dome shape was okay, but the bore spacing was wrong which showed up with the clay check.

One rule that I think everybody will agree - NEVER use any parts out of the box regardless of the vendor! Have a good builder check and remachine as required.

I have decided to go ahead and build a 472 inch motor with mine. Mine will be in a street car and around 10-10.5 compression. I already have the dick landy roller rockers and a set of roller lifters. I plan on getting a camshaft in the 575-600 lift range. With the compression in that area is there still a possible head problem? I looked at the idy website and you can buy a rotating assembly for $1950 from them.

That's what I did
He had a set of cnc indy heads the last time I was there. The ports are the size of the millennium heads and the flow is nowhere near.
