Cometic MLS cylinder head gasket for Pontiac 400/428/455 V8 applications, offered with a nominal .086 in thickness and a 4.200 in bore; the gasket uses embossed stainless steel layers with Viton coating. An uncoated stainless shim layer lets thickness be varied, while MLS construction seals dissimilar head and block materials without sealants. The design reduces required clamp load and helps conform load distribution across the sealing area.
