Product Details

Cometic Gasket is well-known for making solid sealing solutions for performance engines. This MLX head gasket is built for GM LS Gen-3/4 small block V8 engines, featuring a 4.150 inch bore and a .040 inch thickness. It's designed to handle the demands of high output applications, ensuring a reliable seal between your cylinder head and engine block.

This gasket uses a Multi-Layer Steel (MLS) construction, which means it's made of several 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, making it suitable for sealing against aluminum heads on either aluminum or cast iron blocks. The center layer is uncoated stainless steel, and the overall compressed thickness is .036 inches. This construction means you don't need any additional sealants for installation.

This gasket fits a wide range of vehicles, including models like the Chevrolet Silverado 1500, Chevrolet Corvette, and Cadillac CTS. It's a well-built option for anyone rebuilding or modifying their LS engine.
