PROCOMP LS6 heads?
 
Can anyone give me any input on these heads? All i could find for info on these heads is that they have 190cc intake runners, 64cc combustion chambers, CNC'd runners/combustion chambers, and they support 500+ horsepower. What i'd really like to know is he anyone has ever flow tested these or have any dyno results. The only reason i'm interested in these is cuz a buddy of mine is giving me a killer deal on a set. They're new and never installed with stainless valves.

They seem to pop up every once in a while. Not a lot of feedback on LS1Tech but these are all from different posts:

Their rods are scat rods that scat was't happy with not to say their is some defect with them , but they didn't pass inspection for some reason. Their heads are a Patriot reject casting same as a Pbm cheep but you get what you pay for.

Those are pro-comp heads. I would stay clear of them if they're made anything like the procomp SBC heads... You'll need to have the deck squared and lap the valves...

This is a link do a Hot Rod head shootout posting that gave them pretty high marks.

IMO, heads are too important of an item to gamble with. Stick with the models with a proven history.

Funny how you mentioned Pro Comp, as my dad (professional race engine builder since 1971 with over 40 national records) and I were just talking today about how everything that they make is cheap junk...we even discussed how low quality their stainless valves are.
