Cometic GM LS1 SB 4.060 inch Bore .092 inch MLS-5 Head Gasket

Cometic Gasket is a well-known name for creating solid sealing solutions, and this Multi-Layer Steel (MLS) head gasket is a prime example. It's built for GM LS Gen-3/4 small block V8 engines with a 4.060 inch bore, offering a compressed operating thickness of 0.092 inches. This gasket is designed to handle the demands of high-output engines without needing any additional sealants, making installation straightforward.

This MLS gasket 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, ensuring a reliable seal even in harsh conditions. This construction is ideal for mating aluminum heads to either aluminum or cast iron blocks, as it can manage the shearing forces that can 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 popular models like the Chevrolet Camaro, Corvette, and Silverado trucks. It's a solid option for anyone rebuilding or working on the top end of their GM LS engine.
