Cometic GM LS Gen-3/4 Small Block V8 .027in MLS Cylinder Head Gasket-Bore 4.165in

This listing is for a Cometic Multi-Layer Steel (MLS) cylinder head gasket. It features a .027 inch compressed thickness and is designed for a 4.165 inch bore, making it suitable for many GM LS Gen-3 and Gen-4 small block V8 engines. These gaskets are well-built for high output applications and are designed to seal effectively without the need for additional sealants. They work well with both aluminum and cast iron blocks, and can handle the stresses between different metal types.

The gasket is constructed from multiple layers of stainless steel for increased strength and corrosion resistance. The outer layers are coated with Viton, a heat-resistant rubber material that can handle tough sealing conditions and various surface finishes. The center layer is stainless steel and can be varied to achieve different thicknesses, like the .027 inch found in this particular gasket. This design helps ensure a solid seal even under demanding engine loads.

This gasket fits a wide range of GM vehicles, including models like the Chevrolet Camaro, Corvette, and Pontiac GTO. Always check the full fitment guide to confirm compatibility with your specific vehicle.
