The Cometic MLS head gasket for Chevrolet Mark‑IV Big Block V8 (4.510in bore, .051in) is built from multiple embossed stainless steel layers with Viton-coated outer faces for resilient sealing. The center shim layer is uncoated stainless steel and can be varied to meet thickness needs. This layered construction improves clamp load distribution, reduces bore distortion and resists corrosion while handling demanding sealing environments without additional sealants.
