Valve Cover Gasket Set SBC 12 & 18 Degree Heads

The Valve Cover Gasket Set SBC 12 & 18 Degree Heads is a precision engine sealing component engineered for small-block Chevrolet platforms with either 12-degree or 18-degree cylinder head configurations. This gasket set serves as a critical barrier between the valve cover and cylinder head, preventing oil leakage while maintaining proper engine bay integrity. Whether you're rebuilding a high-performance tactical vehicle engine, restoring classic American muscle, or maintaining fleet equipment, this MAHLE ORIGINAL gasket set delivers OEM-grade reliability and proven durability in demanding operational environments.

Manufactured by MAHLE ORIGINAL/CLEVITE—a trusted supplier for law enforcement and military-grade engine components—this valve cover gasket set utilizes advanced elastomer and cork compound materials that resist thermal cycling, oil degradation, and extreme temperature fluctuations. The dual head-angle design (12° and 18°) ensures precise fitment without shimming, eliminating installation variables and guaranteeing a hermetic seal on first install. The gasket geometry is engineered to accommodate OEM bolt torque specifications while maintaining compression integrity across extended duty cycles, making it suitable for both street and high-rpm applications where mission reliability cannot be compromised.

Operators and technicians rely on this gasket set for small-block Chevrolet engines (SBC) commonly found in pursuit vehicles, utility platforms, and specialty automotive builds. Installation is straightforward—remove the existing valve cover, clean the sealing surfaces to bare metal, and install the new gasket set with factory-spec bolt torque (typically 80–100 in-lbs). This complete set eliminates the need for sourcing individual gaskets and ensures all sealing points are addressed in one service interval, reducing downtime and labor cost on fleet maintenance operations or engine rebuilds.
