Cometic GM 2.5L Vortec 3000 153 .120in MLS Cylinder Head Gasket - 4.100in Bore

This Multi-Layer Steel (MLS) head gasket from Cometic is built with a compressed operating thickness of 0.098 inches and features a 4.100 inch bore, making it a solid choice for your 1962-1968 Chevrolet Chevy II. MLS gaskets are constructed from multiple layers of stainless steel, which gives them strength and the ability to rebound, helping them resist corrosion and handle the stresses of high-output engines. They are also well-suited for mating aluminum heads to cast iron blocks, as they can manage the shearing forces that arise between these different materials.

The outer layers of this gasket are coated on both sides with Viton, a heat-resistant rubber material capable of withstanding temperatures up to 482 degrees Fahrenheit. This coating is designed to perform reliably in demanding sealing environments and under various load conditions. The center layer is uncoated stainless steel, and Cometic uses these shim layers to achieve different thickness requirements, like the .120 inch thickness specified for this particular gasket. Because of their advanced construction, MLS gaskets do not require any additional sealants for installation.
