    read the bottom paragraph. it says that if you are on less of a budget, to get Si parts and tranny too.

    also, i've heard that the pistons need to be changed in order for this to work, due to the 8 valve reliefs. perhaps chet can answer that for you in more detial.

    They are the same head, the cam and springs are different, but that's about it.
