This Cometic MLS head gasket fits the Nissan RB26DETT with an 87mm bore and a compressed operating thickness of 0.040 inches. It uses multiple embossed stainless steel layers with Viton-coated outer faces to provide robust sealing in high-output engines. The multi-layer design maintains sealing performance between dissimilar head and block materials and distributes clamp load to reduce bore distortion without added sealant.
