I have conformatic pistons I assume they were
made not round ?? as all measure about .013 difference
at 90 degrees. tne old rings had the dot and the beveled inside facing up both rings. NOW I got a new set of sealed power E237X the sealed power instructions shows to put dot up which has the beveled edge facing down on the second ring groove.and the unmarked ring
i assume in top groove thou it doesnt say that says
unidentified rings may be installed either side up.
is this set ok to use ???
