Help!!! Flycutting?
Guys, a friend and I are in the middle of a pretty big cam install and already have flycut the pistons but don't know if they're cut enough. The cam is a Comp 242/248 .610/.615 111 lsa, heads are AFR milled .034 and we're going to use .040 Cometics. The intakes have been notched about .100 and the exhausts about .060. After claying intakes have about .080 clearance and exhausts .090, is .090 enough on the exhausts or should we cut more? I don't want to destroy this engine , my friend will KILL me . Help.
