is what I said about the GT40x's true? IE... i could still use my headers? What type of codes should I look for to get the right ones?
The GT40X heads do not require any special headers but they do use the pedestal style rocker arms so that must be considered. You can take them to a machine shop and have screw in studs and guideplates installed but it will up the entry price a bit. I have no idea what you are talking about looking for the right codes??
