Graphite intake gaskets - Sealer or no sealer?

I've got these Victor Reinz Nitroseal graphite impregnated intake gaskets for my 347. So, the question is, do I install these things dry or what? There are no specific installation instructions with it, and all the intake manifold install guides I can find are using regular old style Fel-Pro gaskets without any kind of graphite material on them, and they all say to use RTV around the coolant ports. Are graphite gaskets meant to be installed completely free of any sealer? I feel like the graphite would be rendered useless if I covered it with RTV. Gut instinct tells me they're designed to be used dry.

Run them Dry. RTV on the corners at the intersection of the rails for acros the top of the block.
Graphite is meant to allow the expansion of parts..easily... while maintaining the seal. Especially where the heads are cast Iron and the intake is aluminum, or both are aluminum
Fact is stranger than Fiction
