Piston clearance is going to vary based on what cylinder and piston you have. Cylinders will usually be marked A,B or C. A being smaller than C, however there is only very small difference in those like 0.0005" between them.

Target 0.002-0.0025" clearance on piston to wall. Shoot for 0.012-0.016" on the ring gap.
