Cometic's MLS-5 head gasket for Chevy small-block 350/400 V8s is a 0.080" compressed-thickness multi-layer steel gasket with a 4.165" bore and steam holes. The embossed outer stainless layers are coated with Viton to resist heat and chemical exposure, while the uncoated shim layer allows thickness variation. MLS construction seals high-output engines without sealants, conforms load distribution and reduces clamp load requirements.
