The metal ones are available at the dealer. I linked to that particular thread because it gave you the P/N. Here'* one where the LI gasket was replaced w/metal:

I have a friend that works for a local GM dealer so I was able to get the GM revised UIM the UIM gasket TB gasket kit, and lower intake gaskets for $120.00 total. One good thing...the lower gasket is made of some sort of metal and looks to be much better. I'm also having them install a 180 degree thermostat.
I've got a call in to the local dealership here to check on availability (it'* too early for them). I'll let you know what I find.
