Product Details
This Cometic Multi-Layer Steel (MLS) head gasket is what you get in the box for your 1977-1979 BMW 320i. It's built with multiple layers of stainless steel, with the outer layers coated in Viton rubber. This design means it's ready to go right out of the package, no extra sealants needed, and it's built to handle the demands of high-output engines.
MLS gaskets are a solid choice for sealing aluminum heads to either aluminum or cast iron blocks because they can handle the different expansion rates. The stainless steel layers give this gasket strength and help it resist corrosion, while the Viton coating on the outer layers is heat resistant up to 482 degrees Fahrenheit, making it suitable for tough sealing jobs. The center layer is stainless steel and can be varied in thickness; in this case, it's set to provide a compressed operating thickness of .140 inches, matching the bore size of 81mm for the M20B20 engine.
