4.155 MLS Head Gasket .027 - SBF

The 4.155 MLS Head Gasket .027 - SBF is a high-performance sealing component specifically designed for Small Block Ford engines. It serves as a critical barrier between the cylinder head and block, effectively separating combustion pressure from coolant passages. This gasket is ideal for those rebuilding classic 5.0 engine bays, refreshing tired 302s, or assembling stroker platforms.

Engineered by Cometic Gaskets, this multi-layer steel (MLS) design is built to withstand the demands of high-performance builds where stock gaskets may fail. The .027-inch thickness is tailored to ensure the correct combustion chamber volume and compression ratio, making it a precise fit for your Small Block Ford. The MLS technology utilizes alternating layers of spring steel and elastomer, creating a self-sealing surface that adapts to variations in head and block deck finishes.

This gasket is suitable for Small Block Ford engines with a bore diameter of 4.155 inches, ensuring compatibility across various engine displacements. Technicians and engine builders trust Cometic for both stock restorations and modified platforms, with the MLS design capable of handling sustained heat cycles and supporting power levels up to 600+ horsepower.
