Well Ted lapping the flats of the rings of course. Grinding the OD of the rings to match the ID of the cylinder bore with a torque plate in place. We also experimented with Surface texture and the face angles until we found what we liked.
I’m not a fan of barrel faced rings. Even in a perfect world they leak on initial pressure and vacuum. The engine will be smoother because of that but blow by is up slightly and power suffers full range due to compression leakage and lack of intake vacuum.
