The Cometic MLS cylinder head gasket for Holden 253/304/308 V8 engines (4.200in bore, .045in nominal) uses embossed stainless-steel outer layers coated with Viton and an uncoated shim center to deliver reliable sealing. Suited to high-output engines, it requires no sealants, withstands differing head and block materials, resists corrosion, and distributes clamp load to limit bore distortion in aluminum-to-aluminum or aluminum-to-iron installations.
