The Cometic MLS cylinder head gasket for BMC 1275 A-Series (74mm bore) in .030 in nominal thickness provides a multi-layer steel sealing solution for higher-output engines that does not require sealants. Embossed stainless layers with Viton-coated outer faces and an uncoated shim center allow controlled rebound, resist corrosion and shearing between aluminum and iron, and help spread clamp load to reduce bore distortion.
