I just received an MLS exhaust manifold gasket (it's two pieces of steel riveted together). The steel appears to just be plain stainless without any coating on either side of the layers. Has anyone ever used a gasket like this and is this normal? MLS head gaskets usually have a black coating somewhere either on the outside or between the layers, but I assume that's because they have to deal with combustion pressures and not just exhaust being pumped out of a cylinder by a piston under no compression?
Just wondering if anyone has ever used ones like these or if there's anything wrong with these or if these types are supposed to be like this.
It's this gasket:
