Cometic .062" MLS head gasket for Chevrolet Mark‑IV Big Block V8 with a 4.320" bore (right side). Built from multiple embossed stainless steel layers with Viton‑coated outer faces for heat and corrosion resistance, the uncoated center shim allows thickness variation. The multi‑layer steel design rebounds under load, conforms seal loads across the combustion area, and reduces clamp load‑related bore distortion for dependable sealing.
