Cometic GM LS Gen-3/4 Small Block V8 .089in MLS Cylinder Head Gasket - 4.100in Bore

Cometic Gasket is known for making well-built sealing components, and this Multi-Layer Steel (MLS) head gasket is a prime example. If you're working on a GM LS Gen-3 or Gen-4 small block V8 engine, this gasket is designed to provide a strong seal between your cylinder head and block. It's built with multiple layers of stainless steel, which gives it strength and helps it resist corrosion, while the outer layers are coated with Viton, a heat-resistant rubber material that can handle tough sealing environments. This construction means it doesn't require any additional sealants, making installation more straightforward.

The multi-layer steel design is particularly useful when mating aluminum heads to aluminum or cast iron blocks, as it can handle the shearing forces that can occur between different metals. The center layer is stainless steel and can be varied to achieve different compressed thicknesses, and in this case, it's set up for a 0.089-inch compressed thickness with a 4.100-inch bore. This gasket fits a wide range of GM vehicles, including models like the Chevrolet Corvette, Cadillac CTS, and Buick LaCrosse, among many others.
