I had no luck with stock rings they all start off at 150 LBS compression, but a few hunded miles latter that number changes i seen 135 in less than 300 miles ,and then flake.
the Chrome kimpex rings or SPI have way more tension on the cylinder wall on on a fresh cylinder i got 150 lbs and 200 miles latter im up to 160 lbs , all tests are on a cold engine at room temp.and same tester each time,I think there going to be good , only time will tell.
