Cometic MLS cylinder head gasket for Ford Big Block with 4.400" bore and 0.040" compressed thickness uses multiple embossed stainless steel layers with Viton-coated outer faces for heat-resistant sealing. MLS construction allows reliable sealing between aluminum and cast-iron combinations without sealants, distributes clamp load to reduce bore distortion and resists corrosion while meeting demands of high-output engines.
