I think they're around 4-6 layers thick, and the layers are kinda necessary to make a good seal.

Again, if someone knows the material of construction of the OEM gasket, and can provide me an upper limit on operating temperature, I'll look in to what it would take to get gaskets made.

Many different materials are available for both the center core and the compressible material. The selection of these is dependent on service temperature, pressure and chemicals in the piping. IMHO, this type of gasket would actually seal better than an all metal gasket. The downside would be that they are not meant to be reuseable.

I bought mine from Ray Crowe, he takes care of use RX-7 owners.
It is an expensive gasket but it is in a very VERY stressed location, probably seeing the highest temperatures of the entire engine. I think Jonski reused his with success but my origanal one wasnt sealing very well on the back side so I just replaced it. I thought I had lost it a few days ago when I was getting ready to install it... drove me mad to think I lost a 75$ gasket.

As far as the operating temp limit goes, what dgeesaman said would be a safe limit although it was my understanding that EGT's in the 1200F range were considered very high and that standard fell short of 1000F. However, I myself don't have an EGT guage and am going off what I've read from others.
