4.200 MLS Head Gasket .070 - SBC

The 4.200 MLS Head Gasket .070 - SBC from Cometic Gaskets is designed for serious small-block Chevy builders who require reliability under high compression and elevated boost conditions. This gasket is essential for those running stroker builds, forced induction, or nitrous oxide on an SBC platform, as it effectively seals combustion pressure and prevents failures between the block and cylinder head.

Constructed from Cometic's proven multi-layer steel (MLS), this head gasket offers superior sealing performance and reusability compared to traditional composite gaskets. The .070-inch thickness is specifically calibrated for applications requiring precise deck height control, ensuring optimal combustion characteristics when paired with standard SBC deck heights and head configurations. Cometic's proprietary facing and steel-core technology also resists blowby, coolant migration, and thermal cycling, making it ideal for high-performance applications.

Street racers, bracket racers, and high-performance engine builders trust this gasket for naturally aspirated race builds and turbocharged small-block applications. It addresses critical concerns such as head lift, detonation, and sustained RPM, making it a reliable choice for those pushing cylinder pressures beyond stock parameters.
