The paper gasket needs to be glued down with high tack or 3M yellow weatherstrip adhesive on one side and some aviation permatex on the other, if done on oil free surface it will not fail. Silicone on a steel plate that flexes for any reason will shear then leak
Personally I use a coat of Permatex aviation form a Gasket on both mating surfaces, and on both sides of the paper gasket. I let them tack up a bit then mate them carefully. I do this for any paper gasket that my engine has when ever I do repairs or a rebuild. Done right and with clean I mean near medical clean I have had ZERO leaks. The only down side is it's a ****** to take apart if need be.
Valve covers, and pans have no gaskets, I use a reasonable bead of Permatex RTV either grey, the non O2 sensor compatible blue, or some nasty Orange stuff that I used to get from "Cough" Cheby dealership.
The most important aspect is cleanliness before anything else. Then you're almost assured of a leak free bond.
This is just my slightly more than 2cents worth
