Cometic GM LS1 SB 4.160 inch Bore .060 inch MLS-5 Head Gasket

If you're rebuilding the top end of your GM LS Gen-3 or Gen-4 small block V8, getting the cylinder head gasket right is crucial for a reliable seal. This Cometic MLS-5 head gasket is built for engines with a 4.160 inch bore and a compressed thickness of .060 inches, making it a solid choice for many popular GM vehicles like the Chevrolet Silverado, Corvette, and Cadillac CTS.

Cometic's Multi-Layer Steel (MLS) gaskets are well-built with multiple layers of stainless steel for increased strength and resistance to corrosion. The outer layers are coated with Viton, a heat-resistant rubber material that can handle tough sealing environments and varying surface finishes, meaning you won't need extra sealants. The center layer is stainless steel, and its thickness can be adjusted to meet specific requirements, like the .060 inch compressed thickness on this particular gasket. This construction helps them withstand the forces created when mating different block and head materials, such as aluminum to cast iron or aluminum to aluminum.

This gasket is designed to provide maximum sealing performance for high-output engines, ensuring a dependable seal that can handle the demands of your LS engine build.
