Cam timing events are ; Ex. open 53 B.B.D.C. Ex. close 13A.T.D.C. Int. open 13 B.T.D.C. Int. close 53 A.B.D.C. By quench , I'm saying you still have a shallow side of an open combustion chamber. Aprox. .065" from the deck surface. W/ .020" in the hole and .040" gasket.... D'd like to tighten that up , to effectively provide some "QUENCH". Cam timing events are at 1.5 rocker ratio, I'll be using 1.6, not sure exactly how much that effects duration @ .050" I used the calculaters on K.B.' site, effective comp. was about 7.8-7.9
