The Cometic MLS cylinder head gasket for Holden 253/304/308 V8 engines (4.100in bore, .040in nominal) delivers a multi-layer steel seal suitable for high-output builds. Embossed stainless outer layers are Viton-coated and a central uncoated shim layer accommodates thickness needs. The gasket requires no sealants, resists corrosion, and helps distribute clamp load to reduce bore distortion when pairing aluminum heads with aluminum or cast-iron blocks.
