Cometic GM LS Gen-3/4 Small Block V8 .086in 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 Multi-Layer Steel (MLS) cylinder head gasket from Cometic is built to handle the demands of high-output applications. It's designed to provide a solid seal between your cylinder head and engine block, crucial for maintaining compression and preventing leaks in performance builds. This gasket fits a wide range of vehicles, including models like the Chevrolet Corvette, Cadillac CTS, and GMC Sierra 1500.

Cometic constructs these MLS gaskets using multiple layers of stainless steel, which gives them increased strength and the ability to rebound, helping them resist corrosion. The outer layers are coated on both sides with Viton, a heat-resistant rubber material that can handle tough sealing environments and varying surface finishes. This coating, along with the embossed stainless steel layers, means you don't need additional sealants for installation. The center shim layer is stainless steel and can be varied to achieve different compressed thicknesses, with this particular gasket having a compressed operating thickness of 0.036 inches and a 4.000-inch bore diameter.
