Cometic GM LS1 SB 4.100in Bore .040in MLS-5 Head Gasket

This Cometic head gasket is built with a multi-layer steel (MLS) design, using three to five layers of stainless steel. Stainless steel is chosen for its strength, rebound capability, and resistance to corrosion, which are important for a reliable seal. The outer layers of this gasket are embossed and coated on both sides with a Viton rubber material. This coating is heat resistant up to 482°F (250°C) and is designed to handle tough sealing conditions, varying loads, and different surface finishes found in many engines.

This particular gasket is specified for a 4.100 inch bore and has a thickness of .040 inches, making it suitable for GM LS Gen-3 and Gen-4 small block V8 engines. It fits a wide range of vehicles, including models like the Chevrolet Camaro, Corvette, and Silverado, as well as Cadillac CTS and Buick LaCrosse. Ensure this gasket matches your engine's bore size and thickness requirements for a proper seal.
