The Cometic MLS cylinder head gasket for Honda B21A1 (84mm bore) offers a .040in compressed thickness and multi-layer stainless construction to support engine sealing. Embossed outer layers coated with Viton provide heat and chemical resistance while an uncoated shim layer permits thickness customization. MLS gaskets require less clamp load, help limit bore distortion, and seal aluminum-to-aluminum or aluminum-to-cast-iron without sealants.
