Valve Clearance on Larger Camshaft and Flat Top Pistons

When using solid roller lifters, here is a veeeery easy way to check V to P clearance. If you anticipate that you have plenty of V to P clearance, then assemble the engine with the springs you intend to use. Easier with two people. Adjust valve lash & rotate engine until the cyl to be tested is at TDC, on overlap. Simply get a pair vice grips or multigrips & lever up on the prod side of the rocker to push the valve down until it touches the piston. The valve travel is your V to P clearance. When clearance gets tight, you need to check a few degrees before TDC on the exh valve & a few degrees after TDC on the intake valve. You can set up a dial gauge to take the measurement, but I just use a vernier caliper.
