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:

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.

 

Thanks for the input guys! Looks like I'll be going PRC's! When the time comes... Lol
