what kind of heads do you have? stock? aftermarket

Hey, they're ford PI (performance improved) heads, which is what they put on the 1999 and newer gt's. They are from ford, as nobody has come out with an aftermarked head. Many guys are doing the headswap and seeing around 40 horsepower with just the headswap (which include the cams in the heads and everything)

Hope that helps,
