Cometic GM LS1 SB 4.130 inch Bore .060 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 built for GM LS Gen-3 and Gen-4 small block V8 engines, specifically designed for a 4.130-inch bore with a compressed thickness of 0.060 inches. This gasket is a solid option for high-output engines, whether you're working with aluminum heads on an aluminum block or aluminum heads on a cast iron block, as it's made to handle the stresses between different metals.

What makes this gasket stand out is its construction. It uses multiple layers of stainless steel for strength and corrosion resistance, with the outer layers coated in Viton, a heat-resistant rubber material that can handle up to 482 degrees Fahrenheit. This coating ensures a strong seal even in harsh conditions and on various surface finishes, and the center layer can be varied to achieve different thicknesses, like the 0.060-inch spec on this particular gasket. Because it's an MLS design, it doesn't require any additional sealants, making installation more straightforward.

This head gasket fits a wide range of GM vehicles, including popular models like the Chevrolet Corvette, Chevrolet Silverado 1500, and Cadillac CTS. It's a well-made component designed to provide reliable sealing for your engine rebuild.
