Now that the motor is on TDC we will measure the piston on the intake and exhaust sides. When measuring the intake side, push down on the exhaust side, to account for piston rock. We shoot for .040 total and that includes the .027 OEM or Cometic style MLS head gasket. So, we want the piston to be roughly .013 in the hole. I don't see any reason to run it any closer than .040, you decrease Piston to Valve clearance, increase the chance of the piston hitting the head, which will break the rod, and rod stretch.
We use a set of digital calipers, Vernier or dial calipers, and a depth gauge will work fine as well.
