    Going from memory about .o05 per inch of bore …. for example 2 inch bore, would be .01 end gap.

    This gap is not set in stone, it is more a general dimension, as in some applications one needs either more or less end gap

    This is checked by inserting the ring by itself squarely into the bore. I use the bottom of the piston and using a feelers gage to check the gap.
