Jerry, you must have a lot on your mind today because I know that sometime in the past 50 years of hot rodding, you've checked piston deck height with feeler gauges and a steel rule. I explained to this OP how to do it in post #45 and he is reporting back, saying that he has a squish dimension of 0.077" (0.036" piston deck height and 0.041" compressed gasket thickness).
