Cometic Mazda Miata 1.6L 80mm .051 inch MLS Head Gasket B6D Motor

If you're rebuilding the top end of your 1988-1993 Mazda 323, this Cometic Multi-Layer Steel (MLS) head gasket is a solid choice. It's specifically made for the B6D motor and measures 80mm across the bore with a compressed thickness of .051 inches. This gasket is designed to handle the demands of modern engines, providing a reliable seal 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 temperatures up to 482 degrees Fahrenheit. This coating helps ensure a good seal even when you're mating aluminum heads to cast iron blocks, as it can manage the different expansion rates between the metals. The center layer is uncoated stainless steel, and Cometic can vary its thickness for different applications, but this one is set at .051 inches for your specific needs.
