GMPP CNC Heads hey is anyone out there running the GM LS6 CNC ported cylinder heads? (part #88958622).... For the money ($1,140 assembed) are they a good choice? And if so what size pushrods did you go with, as well as the cam? I can only find the 7.400" pushrods when i read that they should use 7.135" pushrods. But the cc's are different now on these heads than when the info im reading was. now heads have 60.99cc, then it was 62cc. would you recommend the LS6 cam or the HOT cam?
I'm goin off a previous setup that was done by Wheel to Wheel Powertrain. I would assume that it's a good setup up since it was built for a road racing corvette.
They also put a 383 stroker in that engine and i know a lot of you run the 408 stroker...How would you think either one would go w/ this setup?
They claimed over 497hp...
If there are heads out there that you feel are better made and more profitable please let me know what your running....Thankz

The price I'm finding is about $1000 PER HEAD...so that's about $2000 total, not $1140 for both. If you are looking for a good head on a budget, look at the PRC heads or Patriots.
I have PRC heads...
