Description
A quality head gasket is the foundation of a reliable, high-compression engine—this MLS gasket delivers the sealing integrity and durability that serious SBC builders demand. The multi-layered steel construction resists blowout under sustained boost and detonation, while the precise 0.045″ compression thickness ensures accurate chamber volumes for tuning consistency. Whether you’re running a naturally aspirated stroker or forced-induction setup, this gasket maintains a critical seal without requiring re-torquing.
