ive been looking at aftermarket irons, and vortecs did cross my mind, but somewhere i thought i remember there being more to the conversion than just the intake and valver covers, i could be wrong though. i know im shooting for a 64cc head, because from what im told that will give me 10:1 comp with the flat top pistons i have. i just wasnt sure about intake runner size and all that good stuff
