The Cometic MLS head gasket for Chevrolet 4.3L Gen‑1 90° V6 (4.060 in bore) features a compressed operating thickness of 0.056 in and a multi‑layer stainless steel construction. Embossed outer layers are coated with Viton for heat and chemical resistance while the center shim is uncoated stainless steel to accommodate thickness needs. MLS gaskets seal aluminum‑to‑aluminum or aluminum‑to‑cast‑iron interfaces without sealants, reducing clamp load and bore distortion.
