Bear with me on this. I broke a crank a while back. Got another crank. Did not note where the crank gear was set on original crank. Nine keyway crank gear. Guessed and aseembled engine. First outing, broke an intake valve and destroyed piston and head. Got new parts, assembled and repeated that fiasco. Two heads, two pistons and major embarrassment!
This is the question. Comp solid roller cam, .715 lift, lobe separation114. intake c/l110. Spec sheets reads; "spc instr for customer. install cam 4 degrees advance, grind instr for cam shop. do not grind advance into cam!!!!" This is taken from the cam build sheet from Comp.
Ok, last build I installed the cam gear at "0". I think I screwed up by 4 degrees. Would that mistake cause the valve problem? Sidenote, 12.8-1 compression, .40 Cometic gaskets
Thanks in adavnce
