Cometic BMC 1500/1600/1600 Mark II B Series .030in MLS Cylinder Head Gasket - 74mm Bore

If you're rebuilding the top end of your 1956-1961 MG MGA, this Multi-Layer Steel (MLS) cylinder head gasket from Cometic is a solid choice. It's specifically made for the B Series engines, including the 1500, 1600, and 1600 Mark II, and comes in a .030 inch undersize to help achieve proper piston-to-head clearance if your block or head has been machined.

This gasket is built with 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 tough sealing conditions and various surface finishes without needing additional sealants. The center layer is uncoated stainless steel, and its thickness can be varied to meet different requirements, like the 0.036 inch compressed operating thickness of this particular gasket. This construction makes it suitable for use with aluminum heads on cast iron blocks, as it can handle the shearing forces that can occur between these different materials.
