The Cometic MLS head gasket for Chevrolet 4.3L Gen‑1 90° V6 (4.060 in bore) is a multi‑layer steel cylinder head gasket with a compressed operating thickness of 0.051 in. Embossed stainless steel outer layers are coated with Viton for heat and sealing resilience while the uncoated center shim permits thickness variation. MLS construction provides strong sealing for aluminum‑to‑aluminum or aluminum‑to‑cast‑iron assemblies without sealants, reduces clamp load and helps limit bore distortion.
