Hi John,
The usual rule of thumb I have heard is 0.003" per inch of piston diameter,
and I also noted discrepancies in this spec when I rebuilt my engine. I
bought a set of rings for my 87.2 mm pistons from Deves and while at it I
asked about this; they told me mine should be 0.011" to (~?)0.015", and
when they arrived by golly they were right on the low end of the spec.
I really think 0.003" will cause you grief.
Regards,
