4.400 MLS Head Gasket .070 BBF FE

The 4.400 MLS Head Gasket .070 BBF FE from Cometic Gaskets is a premium engine sealing solution designed for big-block Ford applications that require precise compression control and reliable combustion chamber integrity. This gasket is ideal for both automotive enthusiasts and professional mechanics who are rebuilding or modifying FE and BBF engines, particularly when OEM gaskets do not meet modern performance demands.

Constructed from multi-layer steel (MLS), this head gasket provides superior clamp load retention and thermal stability compared to traditional composite gaskets. Its .070 inch thickness is specifically engineered for the 4.400 bore diameter, optimizing gasket crush and port flow characteristics while maintaining the proper combustion chamber volume. The elastomer layers bonded to hardened steel substrates allow for micro-movement accommodation, preventing permanent deformation during extreme engine conditions.

This head gasket is essential for builders working on FE and BBF big-block Ford engines, especially those utilizing stock configurations, forced induction, or nitrous setups. Its design ensures leak-free operation under high RPM and elevated cylinder pressures, making it a reliable choice for performance applications. With this gasket, you can expect repeatable and predictable sealing across all eight cylinders, enhancing horsepower and efficiency.
