Cometic GM LS1 SB 4.190 inch Bore .045 inch MLS Head Gasket

When you're rebuilding the top end of your GM LS engine, getting the sealing right is critical. This Cometic Multi-Layer Steel (MLS) head gasket is built for that job, specifically designed for the LS1 and similar Gen-3 and Gen-4 small block V8s. It features a 4.190 inch bore and a compressed thickness of 0.045 inches, making it a solid choice for many performance applications.

What makes these gaskets stand out is their construction. They're made from multiple layers of stainless steel, which gives them strength and helps them resist corrosion. The outer layers are coated with Viton, a heat-resistant rubber material that can handle tough sealing conditions and different surface finishes on your aluminum or cast iron heads and blocks. This advanced design means you don't need any extra sealants, and the gasket can handle the forces between dissimilar metals like aluminum and cast iron.

This gasket fits a wide variety of GM vehicles, from Corvettes and Camaros to Silverado trucks and Cadillac Escalades. It's a well-built component designed to provide reliable sealing for your engine build.
