Cometic GM LS1 SB 4.190in Bore .036in MLS Head Gasket

When you're rebuilding the top end of a GM LS Gen-3 or Gen-4 small block V8, getting the cylinder head sealing right is critical. This Multi-Layer Steel (MLS) head gasket from Cometic is built to handle the demands of high-output engines, ensuring a solid seal between your cylinder head and block. It features a compressed operating thickness of 0.036 inches and a 4.190-inch bore, making it suitable for a wide range of GM LS applications.

Cometic constructs these gaskets from 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 tough sealing environments and various surface finishes, meaning you don't need to add any extra sealants. This design also helps manage the shearing forces that can occur between aluminum heads and cast iron blocks, providing a more robust seal.

This gasket is a solid option for many GM vehicles, including models like the Chevrolet Corvette, Cadillac CTS, and Chevrolet Silverado. It's designed to fit right and perform reliably in demanding conditions.
