Description

The Brian Tooley Racing (BTR) MLS Cylinder Head Gasket Set is designed as a direct replacement for GM's LS1/LS6 head gaskets, fitting 4.8L, 5.3L, and 5.7L engines. This gasket set utilizes a multi-layer steel (MLS) construction, mirroring the quality and design of OEM units. With a bore size of 3.940 inches (99.568mm) and a thickness of 1.33mm, these gaskets are engineered to provide a reliable seal for your engine's combustion chambers and coolant passages. They are manufactured by the same source as the original equipment manufacturer (OEM) gaskets, ensuring a high standard of quality and compatibility. This head gasket set is intended for use in specific GM LS engine applications, providing a durable and effective solution for engine rebuilds or performance modifications.
