i dont think i made my self clear... i already degreed in my cam @ 102 which is +4 from the 106LSA

anyways what im trying to figure out is if i add 1.6 rockers, upping valve lift after lash from .465 to .525 weither i'll need reliefs in the pistons and how deep...

ive never had to check before...
