Product Details
If you're rebuilding the top end of your 1988-1993 Mazda 323, this Multi-Layer Steel (MLS) head gasket from Cometic is a solid choice. It's specifically made for the Mazda B6D motor and has a bore size of 80mm, with a compressed thickness of 0.027 inches. This gasket is designed to handle the demands of high-output engines, providing a reliable seal without needing any extra sealants.
Cometic builds these MLS gaskets with multiple layers of stainless steel for increased strength and resistance to corrosion. 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 have aluminum heads on an aluminum or cast iron block, as it can manage the shearing forces between different metals. The center layer is also stainless steel, allowing for variations in thickness to meet specific engine requirements.
