Any experience with these intake manifold gaskets?
I made the mistake of re-using the stock metal intake manifold gaskets during my rebuild and I ended up with a fuel smell and issues with that. So I pulled the twins and both manifolds and the metal gasket from the LIM to the engine was wet and there was fuel getting past it.
Looking at new gaskets for the intake manifolds I came across these "thermal barrier" ones on ebay.
Does anyone have experience with them? They are cheaper than OEM, and are supposedly reusable, so if they seal well on their own, then I am sold.

There is some info in this thread: https://www.rx7club.com/single-turbo-rx-7s-23/thermal-barier-intake-gasket-801794/
I would recheck torque periodically as teflon is soft and does cold flow somewhat.

I had a customer that claimed they were reusable and insisted that he wanted them on the car. I didn't have an issue with that particular car but the gasket surface definitely had depressions from being tightened down. Also, if you have a fuel smell you most likely have more than a vacuum leak.

I used the oem steel gaskets on both sides of the phenolic plate, if that's what you are asking. The phenolic is very hard and flat and doesn't move at all. No sealing issues whatsoever, and re-torquing is not necessary. You could probably get away with using a sealer on the spacer with no gaskets per se; however, I have not tried it.
I cannot speak directly to the use of teflon gaskets as I have not tried them.
What I can tell you is that the use of thermal barriers makes a big difference in the spread of heat and the reduction of engine bay temps.
