Cometic GM LS Gen-3/4 Small Block V8 .044in MLX Cylinder Head Gasket - 4.040in Bore

When you're rebuilding the top end of your GM LS Gen-3/4 Small Block V8, you'll get a pair of Cometic MLX Multi-Layer Steel head gaskets in this package. These gaskets are built with multiple layers of stainless steel, giving them strength and resistance to corrosion. The outer layers are coated with Viton, a heat-resistant rubber material that can handle tough sealing conditions and various surface finishes, ensuring a solid seal between your cylinder heads and the block. This specific gasket is designed for a 4.040-inch bore and has a compressed thickness of .036 inches, making it suitable for a wide range of LS engines found in vehicles like the Chevrolet Silverado, Cadillac CTS, and Chevrolet Corvette.

Cometic's MLS gaskets are designed to provide maximum sealing performance for high-output engines and don't require any additional sealants. They work well with both aluminum and cast iron blocks, and can handle the different expansion and contraction rates between aluminum heads and iron blocks. The center layer is stainless steel and can be varied to achieve different thicknesses, like the .044-inch thickness of this particular gasket, which results in a .036-inch compressed operating thickness. This construction helps them withstand the shearing forces that can occur in these engine combinations.
