The Cometic MLS head gasket for Nissan RB30 6-cylinder engines fits an 87mm bore with a compressed operating thickness of 0.120". It uses multiple embossed stainless-steel layers with Viton-coated outer faces and an uncoated stainless shim layer to control thickness. MLS construction resists corrosion, requires no sealants and helps manage clamp loads between aluminum and iron mating surfaces for reliable sealing.
