Cometic GM LS1 SB 4.130 inch Bore .070 inch MLS-5 Head Gasket

This is a Cometic MLS-5 head gasket, designed for GM LS Gen-3 and Gen-4 small block V8 engines. You get one multi-layer steel gasket with a 4.130 inch bore and a compressed thickness of 0.070 inches. This gasket is built to handle the demands of high-output engines, offering a strong seal without needing additional sealants.

Cometic uses multiple layers of stainless steel for increased strength and corrosion resistance. The outer layers are coated with Viton, a heat-resistant rubber material that can handle temperatures up to 482 degrees Fahrenheit. This construction is ideal for sealing aluminum heads to either aluminum or cast iron blocks, as it can manage the shearing forces that occur between different metals. The center layer is uncoated stainless steel, allowing for precise thickness control.

This gasket fits a wide range of vehicles, including models like the Chevrolet Camaro, Corvette, and Silverado trucks. It's a solid option for rebuilding or upgrading your LS engine.
