Cometic MLS head gasket for GM Gen‑V/VI Big Block V8 with a 4.630‑inch bore and 0.098" compressed thickness. Composed of multiple embossed stainless steel layers with Viton‑coated outer faces, it resists corrosion and seals without additional sealants. The uncoated center shim allows thickness tuning and rebound, and the embossed layers distribute load to lower clamp requirements and limit bore distortion between aluminum and cast‑iron mating surfaces.
