Cometic GM LS1 SB 4.160 inch Bore .036 inch MLS Head Gasket

This product includes one Cometic Multi-Layer Steel (MLS) head gasket designed for GM LS Gen-3/4 small block V8 engines. It features a 4.160 inch bore and a compressed thickness of 0.036 inches. These gaskets are built to handle the demands of high-output engines and are suitable for use with both aluminum and cast iron blocks, as they can manage the shearing forces between different metals.

The construction uses 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 temperatures up to 482 degrees Fahrenheit (250 C), ensuring a reliable seal in harsh conditions. The center layer is uncoated stainless steel, allowing for precise thickness control. Because they are well-built with advanced materials, these MLS gaskets do not require any additional sealants.

This gasket fits a wide range of GM vehicles, including models like the Chevrolet Corvette, Cadillac CTS, and Chevrolet Silverado 1500. Always refer to the manufacturer's installation instructions for proper fitment and procedures.
