Cometic GM LSX Gen-4 Small Block V8 .120in MLS Cylinder Head Gasket - 4.185in Bore - RHS

This Cometic Multi-Layer Steel (MLS) head gasket is built with three layers of stainless steel, featuring a Viton rubber coating on the outer layers. This construction is designed to handle the high output demands of GM LSX Gen-4 Small Block V8 engines, offering maximum sealing performance without needing additional sealants. The Viton coating is heat resistant up to 482 degrees Fahrenheit, making it suitable for a variety of harsh sealing environments and surface finishes.

The multiple stainless steel layers provide increased strength and the ability to rebound, which helps resist corrosion and withstand the shearing forces between aluminum heads and aluminum or cast iron blocks. The center shim layer is uncoated stainless steel and can be varied to achieve different compressed thicknesses, with this particular gasket having a compressed operating thickness of 0.098 inches from its 0.120-inch uncompressed size. This well-built gasket is a solid option for rebuilding or upgrading your LSX engine.
