The Cometic MLS cylinder head gasket for BMC 1275 A-Series (74mm bore) in .140 in nominal thickness supplies a robust multi-layer steel sealing solution for high-output engines without sealants. Embossed stainless outer layers coated with Viton combined with an uncoated center shim allow the gasket to resist shearing between aluminum and iron, rebound against corrosion, and distribute clamp load to reduce bore distortion.
