Cometic GM LS Gen-3/4 Small Block V8 .054in MLS Cylinder Head Gasket - 3.910in Bore

If you're working on a GM LS Gen-3 or Gen-4 small block V8, this Cometic Multi-Layer Steel (MLS) cylinder head gasket is a solid choice for sealing your engine. It's designed with a 3.910-inch bore and a compressed thickness of .054 inches, making it suitable for a wide range of popular GM vehicles like the Chevrolet Silverado, GMC Sierra, and Cadillac Escalade.

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 various surface finishes without needing additional sealants. The center layer is stainless steel, and its thickness can be varied to meet different engine build requirements. This construction helps them withstand the forces created when mating aluminum heads to cast iron blocks, or aluminum to aluminum.

These gaskets are a good option when you need dependable sealing for a performance-oriented engine build. Just be sure to check the manufacturer's instructions for any specific installation requirements for your application.
