Cometic GM LS1 SB 4.060 inch Bore .051 inch MLS 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 4.060-inch bore with a compressed thickness of .051 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.

The construction 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 strong seal even in demanding conditions. This design means you don't need to use any additional sealants, making installation more straightforward. The center layer is uncoated stainless steel and can be varied to achieve different thickness requirements, which is how Cometic offers a range of gasket options.

This gasket fits a wide variety of GM vehicles, including popular models like the Chevrolet Corvette, Camaro, and Silverado trucks. It's a well-made component designed for reliable sealing in performance applications.
