Cometic MLS head gasket for Chevrolet Gen‑1 Small Block V8 with a 4.165" bore, .030" compressed thickness and full steam holes. It seals modern high‑output engines without additional sealants and suits aluminum‑to‑aluminum or aluminum‑to‑cast‑iron applications. Constructed from embossed stainless steel layers with Viton‑coated outer faces and an uncoated shim layer. The design rebounds, resists corrosion, lowers clamp load and evens sealing pressure around the bore.
