Cometic BMC 1275 A-Series .080in MLS Cylinder Head Gasket - 74mm Bore

If you're rebuilding the top end of your 1967-1974 MG Midget's A-Series engine, a quality head gasket is crucial for a proper seal. This Multi-Layer Steel (MLS) gasket from Cometic is built to handle the demands of performance engines, ensuring your combustion chambers stay sealed tight.

This gasket is constructed from multiple layers of stainless steel, which gives it increased strength and resistance to corrosion. The outer layers are coated with Viton, a heat-resistant rubber material that can handle high temperatures and various sealing environments without needing additional sealants. 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 .036 inches, with a bore size of 74mm, specifically for the 1275 A-Series engine. This design makes it suitable for mating aluminum heads to either aluminum or cast iron blocks, as it can manage the different expansion rates between these materials.

This gasket is designed as a direct replacement for your stock unit, fitting right into place for a straightforward installation when you're putting your engine back together.
