Just wondering what kind of gains you guys are seeing with Patriot Stage 2 LS6 heads on a car that already has full bolt ons and a cam. I think those are the heads i'm gonna go with and i'm curious to find out.

I figured they'd be worth at least 40 but i guess it also has to do with the tune.

A lot of that has to do with your cam also.

very true, both are factors (cam size/selection and tune). i have a baby cam with that 224, but dont get me wrong, the car is strong...

also, its worth noting, Patriot does sell Stage II Ls6 heads and Stage II Ls6 "Style" heads. The Ls6 "Style" heads are 6.0L heads welded up to the 'cc' size of your choice. I am not sure how the Ls6 heads are done, and you might want to double check to make sure those heads are 5.7 or 6.0L heads...
