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.

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.
