[QUOTE="alwaysdiesel, post: 1543149, member: 14250"] Rechecked all measurements: Piston protrusion checked with dial ind= 0.033" Valve recession = 0.025" Head thickness = 3.735" I've made myself a set of solid lifters using round stock and shims, and bought some comp cams adjustable pushrods. Set pushrods to zero valve lash, and rolled it over. On valve overlap, intake clearance is 0.015", and exhaust clearance is 0.025" at tightest points. So pistons came back out to get machined down. Question is, how much can I take off? Spec is 0.008" minimum protrusion out of deck, but can I run them slightly below deck? I don't care about losing some compression, I just don't want anything touching. At this point, I can take 0.025" off and be at minimum heigh spec but would prefer to take closer to 0.040" off and increase my intake clearance to 0.055" [/QUOTE]
