I was always under the impression that the rings had to be seated to the
cyl they'd be working in, because the polish/hone patterns would be
different between bores. The rings may seat well in the "spare" liner, but
then would have to re-seat all over again in the cyl they were destined
for... I'd think that would cause excessive wear and increase end gaps.
Later,
