Cometic BMC 1275 A-Series .051in MLS Cylinder Head Gasket - 73mm Bore

The outer layers of this Cometic Multi-Layer Steel (MLS) head gasket are coated with Viton, a heat-resistant rubber material that can handle temperatures up to 482 degrees Fahrenheit. This gasket is built with a compressed operating thickness of 0.051 inches and a 73mm bore, specifically designed for the 1275cc A-Series engine found in your 1967-1974 MG Midget.

MLS head gaskets are well-built for high-output engines because they use multiple layers of stainless steel. This construction gives them increased strength and the ability to rebound, which helps them resist corrosion and maintain a seal. Because they're made of multiple stainless steel layers, they can handle the shearing forces that occur when you have aluminum heads bolted to cast iron blocks, making them a solid choice for many engine builds. These gaskets don't require any additional sealants, simplifying installation.
