Cometic GM LS1 SB 4.060 inch Bore .075 inch MLS-5 Head Gasket

If you're rebuilding the top end of a GM LS Gen-3 or Gen-4 small block V8, getting the right head gasket is crucial for a solid seal. This Multi-Layer Steel (MLS) gasket from Cometic is built for high-output engines and is designed to handle the demands of both aluminum and cast iron blocks. With a 4.060 inch bore and a compressed thickness of 0.075 inches, it's a popular choice for many LS engine builds.

Cometic constructs these MLS gaskets from multiple layers of stainless steel, which gives them strength and the ability to rebound, helping to prevent corrosion. The outer layers are coated with Viton, a heat-resistant rubber material that can handle temperatures up to 482 degrees Fahrenheit. This advanced coating ensures a reliable seal even under tough conditions and across different surface finishes, and you won't need any extra sealants with these gaskets.

This gasket fits a wide range of GM vehicles, including models like the Chevrolet Corvette, Cadillac CTS, and Chevrolet Silverado 1500. It's a well-built option for anyone looking to ensure a leak-free seal on their LS engine.
