I used to use them back in the '80s in circle track stuff. All impressed with near zero leak down numbers. No dyno testing to prove them. My stuff was as fast as anybodies, but found later it wasn't the rings. LOL everybody else around here was using them too. A monkey-see-monkey-do kind of deal, I guess. I always used their whole ring pkg, with no oiling problems.

Now I use very narrow Total Seal top rings, their Napier 2nd rings, and my own oil ring combo. I'm now down to 4lbs oil rings. (Love those Napier seconds!) One hand on the dampener to turn my short block. (Less than 5 ft lbs) Still dry up top. Cylinders MUST be straight with the right finish to get away with this! Personally, I would not try this without a diamond hone. Patterson machines my block and sells me many of my parts. I could never make the same power with their gapless rings.
