Cometic MLS cylinder head gasket for Pontiac 400/428/455 V8 engines, offered with a nominal .095 in thickness and a 4.200 in bore. The gasket uses multiple embossed stainless steel layers with Viton coating on both faces and an uncoated stainless shim to accommodate thickness needs. MLS construction provides strong sealing for aluminum or cast‑iron block/head pairings without sealants, while improving load distribution and reducing required clamp load.
