Cometic MLS head gasket for GM Gen‑V/VI Big Block V8 with a 4.630‑inch bore and 0.056" compressed thickness. Multiple embossed stainless layers include Viton‑coated outer faces to resist heat and surface‑finish variation, while an uncoated stainless shim layer provides adjustable thickness and rebound. The MLS design seals high‑output engines without sealants, evens load distribution, and lowers clamp load to reduce bore distortion.
