The Cometic Street Pro top-end gasket kit for the Nissan RB26DETT (87mm bore) includes an .050" MLS cylinder head gasket and a full set of gaskets and seals needed for a rebuild. StreetPro kits prioritize quality materials—MLS, AFM, aramid fiber, and Armor Clad—and MLS construction provides embossed outer layers with an uncoated stainless shim to distribute load, reduce clamp requirements, and improve sealing under varied surface finishes.
