Athena Top End Gasket Kit for Honda (P400210600239)

The Athena P400210600239 Top End Gasket Kit is designed for professional, semi-professional, and amateur riders who refresh their Honda engine before a race or during the riding season. This service-ready kit provides the essential top-end gaskets needed to support reliable engine assembly and help maintain consistent performance.
The kit includes a premium MLSS head gasket along with two or more high-quality base gaskets in different thicknesses. This selection allows the builder or rider to fine-tune engine compression according to the intended fuel and performance setup. Use the appropriate gasket combination for stock compression with standard gasoline or select a higher-compression configuration for use with race fuel, when compatible with the engine and tuning requirements.
Athena manufactures this top-end gasket kit for dependable fitment and sealing performance during engine rebuilding or midseason maintenance. The MLSS head gasket is engineered for demanding use, while the range of base-gasket thicknesses provides practical flexibility during assembly. Confirm application details and engine specifications before installation to ensure the correct gasket configuration.
The Athena P400210600239 kit does not include valve stem seals, rubber components, shims, or additional fiber gaskets. These items must be sourced separately if required for the engine service. Follow the manufacturer’s installation procedures and torque specifications for proper sealing and long-term reliability.
