Freshing up the 500" stroked 400 after the cylinder head issue, and I am curious if changing the file fit Total seal CR9190-130 rings to a different type or brand would make much difference. The engine is 12.4:1 compression and max RPM is 7,000.

Anyone use the M9190-130 MaxSeal gapless top ring set?
