Cometic BMC 1275 A-Series .066in MLS Cylinder Head Gasket - 74mm Bore

Cometic Gasket is known for making well-built sealing components, and this Multi-Layer Steel (MLS) head gasket is a prime example for your 1967-1974 MG Midget. This gasket is designed to handle the demands of your A-Series engine, ensuring a solid seal between your cylinder head and block. It's built with multiple layers of stainless steel, which gives it strength and resistance to corrosion, and the outer layers are coated with Viton, a heat-resistant rubber material that can handle tough sealing environments.

The multi-layer steel construction is key here. It provides increased strength and allows the gasket to rebound, helping it maintain a seal even with the different expansion rates between aluminum and cast iron blocks. The Viton coating on the embossed outer layers is rated for temperatures up to 482°F (250°C), making it suitable for high-output engines. This gasket has a compressed operating thickness of 0.066 inches and a 74mm bore, designed to fit your specific engine application without needing additional sealants.
