Personally I like the Ultra Black RTV, not to be confused with the regular black RTV. I also stick the manifold right on after applying the RTV, never any issues.
If using a higher quality gasket with a bead stamped into it, install it dry. If it's just a cheap flat paper gasket, applying Indian Head Gasket Shellac does wonders.
