The Cometic MLS head gasket for Nissan RB26DETT (86mm bore) is a multi-layer stainless steel cylinder head gasket specified at .066in with compressed operating references in the product notes. It seals high-output engines without sealants and fits aluminum-to-aluminum or aluminum-to-cast-iron assemblies. Embossed outer layers are Viton-coated for temperature-resistant sealing; the uncoated stainless shim layer enables thickness options, improves rebound, evens sealing pressure, and reduces clamp load induced distortion.
