I'm not familiar with all of the gaskets that you have been discussing, but
in general, gaskets can be both needed and not needed in different
applications. If you are using a very thin gasket, then using a small amount
of RTV on the surface seems to work well, especially to allow the RTV to set
up (assembly aide).
I use to work in a pump repair facility (medium to high energy pumps up to
4,000 psi discharge pressure) and we found that sometimes using no gasket
was better then using a gasket (and non RTV). However, this was on a surface
that was machined to less than 0.001" flat and had a lot of bolts holding it
Answer to the question? Who knows?
