I've been playing around with some option the one I think I may go with is kb167 and set of aluminum heads 58cc that cc includes the 5cc you lose from the valve reliefs in those piston I'll run a felpro head gasket 0.039 and according to the compression calculator should put me around 10.5 I'm going to get bare heads and have them set up at a machine shop as for needing a bigger cam I've debated maybe running 1.6 ratio rockers but not sure and I have a 2500 stall converter and 4.10 gears. I'm still young and learning so try to take it easy on me lol
