Okay, with the head off, the only way I've ever done it, as both valves start to close you bring the piston up and STOP 3/8" BEFORE TDC. If you were going to TDC a then bringing the piston down you were timing it AFTER TDC. Wrong. You can go to TDC and back it off against the direction of normal rotation but why bother?
