The Cometic MLS head gasket for Nissan RB26DETT (87mm bore) is a multi-layer stainless steel cylinder head gasket specified at .056in. It provides sealing without added sealants for aluminum head/block or mixed-material assemblies. Embossed outer layers are coated with Viton for heat tolerance and reliable sealing; the uncoated stainless shim layer supports thickness choices, improves rebound, evens clamp load distribution, and helps reduce bore distortion caused by clamping forces.
