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

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?

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. 
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...

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!

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?
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.
