Cometic BMW M20 2.0L/2.3L 81mm .040 inch MLS Head Gasket 320/320i/520

Cometic Gasket is known for making well-built sealing components, and this Multi-Layer Steel (MLS) head gasket is a prime example. If you're working on the M20 engine in your 1977-1979 BMW 320i, this gasket is built to handle the job. It's designed to provide a strong seal between the cylinder head and the engine block, which is crucial for keeping coolant and oil where they belong and maintaining proper combustion pressure.

This gasket is constructed from multiple layers of stainless steel, giving it increased strength and the ability to rebound, which helps resist corrosion. The outer layers are embossed and coated with Viton, a heat-resistant rubber material that can handle temperatures up to 482°F (250°C). This Viton coating is designed to work well with both aluminum and cast iron engine blocks, and it means you don't need to use any extra sealants during installation. The compressed thickness of this gasket is 0.040 inches, and the bore size is 81mm, specifically matching the M20B20 engine found in your 320i.
