Another day another set of seats. Oversized valves require oversized seats. The factory seats are not larger enough OD to remove the heat properly and will lead to leakage at best. Dropping the seat at worst.
These heads got a fresh surface only needing .0015” cut on the Rottler to clean up.
New guides are sized and ready for the valve job in the morning. Topped off with final blending before assembly.
