Athena Top End Gasket Kit for Honda (P400210600220)

The Athena P400210600220 Top End Gasket Kit is designed for professional, semi-professional, and amateur riders who refresh the engine before a race or during the riding season. This kit provides the essential top-end sealing components needed for engine service and performance-focused maintenance on compatible Honda applications.
The kit includes an Athena MLSS head gasket along with two or more premium-quality base gaskets in different thicknesses. This gasket selection allows riders and technicians to fine-tune engine compression according to the intended fuel and performance setup. Use the appropriate base gasket for standard pump gas with stock compression or select a different thickness when configuring the engine for higher compression and race fuel.
Built for reliable installation and precise engine preparation, the Athena P400210600220 kit supports consistent sealing across the cylinder and crankcase surfaces. It is a practical choice for race preparation, midseason maintenance, and top-end rebuilding when compression adjustment is an important part of the setup.
Please note that this kit does not include valve stem seals, rubber components, shims, or additional fiber gaskets. Verify application compatibility with your Honda model and engine configuration before installation. Follow the manufacturer’s service procedures and torque specifications for proper fitment and dependable performance.
