Hi all, got a couple of questions for you. First off, I have a cam,comp cams retrofit kit, and some rhoads lifters for my 96 indy that I bought off of a good buddy of mine. He never installed them and offered them up to me for a good price! Anyways cam specs are as follows, 264 intake,274 exhaust,112 lobe separation, and.512/.512 valve lift. Will my stock valve springs take this much lift or no? And, will my pistons kiss my valves? I do have some engine experience and want to do this myself, Thx.
