Cometic GM LS Gen-3/4 Small Block V8 .098in MLS Cylinder Head Gasket - 4.000in Bore

If you're working on a GM LS Gen-3 or Gen-4 small block V8 engine, this Cometic Multi-Layer Steel (MLS) head gasket is a solid choice for sealing your cylinders. It's designed with a 4.000-inch bore and a compressed thickness of .098 inches, making it suitable for a wide range of applications, including popular models like the Chevrolet Silverado, Cadillac Escalade, and Buick LaCrosse.

Cometic builds these gaskets with 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 varying surface finishes, ensuring a reliable seal even with aluminum heads on cast iron blocks. The center layer is stainless steel and can be varied to achieve different thicknesses, like the .098 inches on this particular gasket, which is ideal for many performance builds.

These MLS gaskets are designed to provide maximum sealing performance for high-output engines and don't require any additional sealants, simplifying installation. They are well-suited for both aluminum-to-aluminum and aluminum-to-cast iron block configurations.
