Cometic GM LS1 SB 4.060 inch Bore .036 inch MLS Head Gasket

This product includes a pair of Cometic Multi-Layer Steel (MLS) head gaskets, designed for GM LS Gen-3/4 small block V8 engines. Each gasket features a 4.060 inch bore and a compressed thickness of 0.036 inches. These gaskets are built with multiple embossed layers of stainless steel, with the outer layers coated in heat-resistant Viton rubber. This construction helps ensure a strong seal for high-output engines, making them suitable for use with both aluminum and cast iron blocks.

The multi-layer steel design provides increased strength and resistance to corrosion, while the Viton coating on the outer layers meets the demands of harsh sealing environments. The center shim layer is uncoated stainless steel, allowing for precise thickness adjustments. These MLS gaskets are designed to provide maximum sealing performance without the need for additional sealants, and they can effectively handle the shearing forces that can occur between different block materials.

This head gasket set fits a wide range of GM vehicles, including models like the Chevrolet Silverado 1500, Chevrolet Corvette, and Cadillac CTS. They are a solid option for rebuilding or upgrading the top end of your LS engine.
