I have an NOS replacement 60hp block with factory thin wall sleeves. What type of rings work best running in the steel sleeves. Someone here had stated they require a certain ring type. I have Hastings #123, Ford 82A-6149A, and some Ford 82AS-6149A for cast steel pistons on hand. I have both cast steel and aluminum T slot pistons. Also what would be the best Brush ball hone grit to use on the steel sleeves.
