MOCKUP
When I mockup to check for piston to valve clearance or pushrod length, I use cardboard strips to simulate the compressed gasket thickness. I lightly snug down a couple of bolts and save the gaskets for the final assembly. Another handy mockup tip is to wrap masking tape around the ring land area of your piston. Just enough to get the “rock” out and tighten its fit in the bore. No wear and tear on the rings and less chance of breaking or chipping one. I never put in the pin locks during the checking in case adjustments to the valve pockets are needed.
