Thanks I'll double check my math.
Plumbers Crack
OE pistons are JE/SRP similar to #123475, 1cc, 5/64" rings 4.468 (except OE has metric ring lands) These are high silicate (low expansion requires a skirt clearance of .004 to .0045)
They also make a JE 4.469", 123189 with a 4cc dome and 1/16" rings which requires a skirt clearance of .005 to .0055
