So,
if I pulled the heads
and found less than
0.004 inches of ridge (0.008 total wear)
it would be fairly safe to
run an experiment
where cylinders 1, 4, 6, 7
were re-ringed with the Total Seal Gapless
and cylinders 2, 3, 5, 8
were re-ringed with OEM factory Chrysler rings?

Then compare the four cylinders
for compression,
leakdown percent,
power balance on 4 cylinders on a rear wheel dyno?

Or
are there equivalent measurements to make
on the individual piston grooves
to see if they can safely take
new rings?
