Cometic GM LS1 (w/M.I.D. Sleeves) 4.165 inch Bore .066 inch MLS-5 Head Gasket

Cometic Gasket is known for making well-built sealing components, and this Multi-Layer Steel (MLS) head gasket is a prime example. It's designed for GM LS Gen-3 and Gen-4 small block V8 engines, fitting a wide range of vehicles like the Chevrolet Camaro, Corvette, and Pontiac GTO. This gasket is built to handle the demands of high-output engines, ensuring a solid seal between your cylinder head and block without needing any extra sealants.

What makes this gasket stand out is its construction. It uses multiple layers of stainless steel for increased strength and resistance to corrosion, which is important when mating aluminum heads to either aluminum or cast iron blocks. The outer layers are coated with Viton, a heat-resistant rubber material that can handle temperatures up to 482 degrees Fahrenheit and works well in tough sealing environments. The compressed thickness is set at 0.066 inches, and it includes Darton MID Sleeves for improved performance.
