4.200 MLS Head Gasket .075 - SBC

The 4.200 MLS Head Gasket .075 from Cometic Gaskets is designed specifically for small-block Chevy (SBC) builds, ensuring precision compression sealing and durability. This gasket is ideal for both street performance engines and high-RPM competition builds, where consistent compression retention is crucial.

Constructed from Multi-Layer Steel (MLS), this gasket offers superior sealing integrity compared to traditional composite designs. The .075-inch compression thickness is vital for matching your engine's chamber design and piston specifications, preventing issues like detonation or insufficient compression.

Engine builders and mechanics prefer MLS gaskets for applications involving repeated disassembly and high combustion pressures, such as race engines and LS-swap conversions. The 4.200-inch bore diameter ensures compatibility with standard SBC cylinder head packages, whether using stock or ported heads on various SBC platforms.
