Cometic Opel 20E/20N/20S CIH 97mm .045in MLS Head Gasket

This is the Cometic Multi-Layer Steel (MLS) head gasket for your Opel 20E, 20N, or 20S CIH engine. It's built with a 97mm bore and a compressed thickness of .045 inches, designed to seal your cylinder head to the engine block. MLS gaskets are a solid choice for high-output engines because they offer strong sealing performance without needing any extra sealants.

Cometic builds these gaskets with 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 different surface finishes. The center layer is stainless steel and can be varied to achieve different thicknesses, like the .045 inches on this particular gasket. This construction makes them suitable for sealing aluminum heads to aluminum blocks or aluminum heads to cast iron blocks, as they can manage the stresses between different metals.
