The Cometic MLS head gasket for the Nissan RB30 is a multi-layer steel cylinder head gasket engineered with embossed outer layers coated in Viton and an uncoated stainless-steel shim layer, provided at a compressed operating thickness of 0.040" for the 87mm bore. Viton-coated outer layers resist heat up to roughly 250°C (482°F) and fluid exposure, while the MLS construction promotes rebound, corrosion resistance, and consistent sealing across aluminum or cast-iron mating surfaces.
