Cometic MLS head gasket for Chevrolet Small Block is a multi-layer steel design at .080" thickness with a 4.155" bore for 18/23 degree heads. Built from embossed AMP-coated outer layers and an uncoated stainless center shim, the gasket conforms load distribution, requires less clamp load to reduce bore distortion, and accommodates different thickness requirements for demanding sealing environments.
