Cometic GM LS Gen-3/4 Small Block V8 .124in MLS Cylinder Head Gasket - 4.060in Bore

If you're working on a GM LS Gen-3 or Gen-4 small block V8 engine, this Cometic Multi-Layer Steel (MLS) cylinder head gasket is a solid choice for rebuilding or performance work. It's designed with a 4.060-inch bore and a compressed thickness of .124 inches, making it suitable for a wide range of LS applications, including popular models like the Chevrolet Silverado, Corvette, and Cadillac CTS.

Cometic builds these gaskets using 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 conditions and different surface finishes, ensuring a reliable seal without needing extra sealants. The center layer is stainless steel and can be varied to achieve different thicknesses, like the .124 inches on this particular gasket, which is useful for fine-tuning compression ratios or accommodating specific engine builds.

This gasket is a good option for both aluminum-to-aluminum and aluminum-to-cast iron block setups, as the multi-layer steel construction can handle the stresses between dissimilar metals. It's a well-made component designed to perform under the demands of high-output LS engines.
