What you need to do is talk to Keith Jones at Total Seal. He'll tell you straight up what you need to know.

I do not run them, I run various Total Seal Advantage sets as well as Diamond or Gold profile ring sets.

The gap less top ring may work okay, I'd stay far away from gap less second rings.

Rings packages make power. However, trick rings are not a substitute for perfection in bore preparation. It doesn't not matter how much your rings cost, or how trick they are, if your cylinders are not perfectly straight and round, with the correct finish, nothing will work. The flip side of that is that if your bores are as close to perfect as possible, a lot of dynos will be hard pressed to repeatably measure the difference between a killer ring package and a good package.
