The Cometic GM LS1/LS2/LS3/LS6 Gen-3/4 Small Block V8 .040in MLX Head Gasket 4.040in Bore 1/2in Studs - H3313SP3040S is a precision-engineered head gasket with a 4.040" bore and .040" compressed thickness.
The Cometic MLX Multi-Layer Steel (MLS) head gasket is engineered for high-performance and racing applications where OEM gaskets fall short. Featuring MLX Multi-Layer Steel (MLS) construction, this gasket uses multiple embossed steel layers for superior sealing under extreme cylinder pressures and temperatures. Precision CNC-machined to exacting tolerances, this gasket seals combustion, water jackets, and oil passages simultaneously — eliminating the need for multiple gaskets or sealing compounds.
