Cometic MLS head gasket for GM Gen‑V/VI big block V8s with a 4.320 inch bore and 0.098 inch compressed thickness. Composed of multiple embossed stainless steel layers with Viton-coated outer faces and an uncoated stainless shim, the gasket provides MLS sealing without sealants. It tolerates mixed head/block material pairings, resists corrosion, rebounds under load and helps conform clamp load across the sealing surface for demanding engines.
