Description
A top-end gasket kit is essential maintenance for any racer looking to maximize engine reliability between rebuilds. The ATHENA P400485600213 gives you the flexibility to run either pump gas with stock compression or switch to race fuel with elevated compression—letting you optimize your power delivery based on your fuel choice and track conditions. By refreshing your top-end sealing surfaces, you’ll eliminate the risk of combustion blow-by and coolant weeping that can sideline you mid-season.
