What year is your car again? I know it was discussed before in a different thread, but I forgot. The only negative thing I've heard about the TF heads, besides the price, is that on n/a cars they're not really worth it unless you're going to rev it to the moon. Personally, I would just get some Stage 2 Patriot's, slap some nice cams in them and call it done (and for about the same price if not maybe less than the TF heads by themselves).
