Probe piston wall clearance.

Does anybody know how much clearance Probe puts into its SRS pistons. Specifically part number 12351? I measured my bores in my block with a dial bore gauge, and came out with 4.0442 on the top of the thrust side of cyl 6 and 4.0438 at the same place on Cyl 8.

All the other cylinders are showing 4.0430 or less. Taper is under .0008 for all cylinders except for 3 (.0009), 6 (.0011) and 8 (.0018

Is there enough meat to use the probe pistons with the wall gap on the high side?
