Cometic GM LS1 SB 4.130 inch Bore .080 inch MLS-5 Head Gasket

Cometic Gasket has a reputation for making solid engine components, and this Multi-Layer Steel (MLS) head gasket is a great example. It's built for GM LS Gen-3 and Gen-4 small block V8 engines, specifically designed for a 4.130 inch bore with a compressed thickness of 0.080 inches. This gasket is ideal for high-output engines, whether you're pairing aluminum heads with an aluminum block or cast iron block, as the multi-layer steel construction can handle the shearing forces between different metals.

What makes these MLS gaskets stand out is their strength and sealing capability. They're made from multiple layers of stainless steel, which gives them the ability to rebound and resist corrosion. The outer layers are embossed and coated with Viton, a heat-resistant rubber material that can handle tough sealing environments and various surface finishes. The center layer is uncoated stainless steel and can be varied to achieve different thicknesses, like the 0.080 inch on this particular gasket. Because of this advanced construction, they don't require any additional sealants.

This head gasket fits a wide range of GM vehicles, including models like the Chevrolet Camaro, Corvette, and Silverado trucks. It's a well-built part designed to provide maximum sealing performance for your engine build.
