The LS3/L92 MLS Head Gasket – 4.080 Bore x .051 from Chevrolet Performance is an essential component for LS-platform engine builders and performance enthusiasts who demand OEM-quality reliability. This multi-layer steel (MLS) gasket is specifically designed for the LS3 and L92 cylinder heads, ensuring optimal sealing integrity for modern forced-induction builds and high-rpm applications.

Constructed with layered steel and elastomer coatings, this gasket provides a superior seal across varying cylinder pressures and thermal cycles. The precision-engineered 4.080-inch bore and .051-inch thickness are tailored for LS3 and L92 heads, promoting proper clamp load distribution and preventing compression loss. This factory-spec design simplifies gasket selection, making it ideal for both stock rebuilds and custom LS swaps.

Engine builders will appreciate the MLS construction, which resists degradation from ethanol fuels and coolant additives, thereby extending the service life of their rebuilds. This gasket is compatible with LS3 and L92 cylinder heads, making it a versatile choice for various applications, including 4th-gen Camaros and 5th-gen trucks.
