But there is a "Quick and Dirty" way to measure head clearance nobody has mentioned. Oil the piston and head, put a small dab of your kid's modeling clay on the piston. Screw the head down and turn the crank through TDC, pull the head and measure the thickness of the clay dab. You're done, leave it all alone or change the shim, whatever you want.

That's a great idea that I've never thought of. I guess I wouldn't be because I'm not a Race Car Builder like yourself.
The usual way we measure these little engines is STROKE=TDC-BDC.
But thanks for the tip!
