After the block was checked and prepped with a cylinder hone and a cam bearing install, it was time to do some ring fitment. The factory spec for the compression-ring endgap in this application is .010- to .020-inch. Since we ordered a basic kit from Summit, we thought this would not be an issue. We were right-the gaps came in at .017-inch. We used the piston assembly to make sure the rings were square in the bores.
