The thing about sealing these early air-cooled engines is that most ideas/techniques "can/may" work. We offer a technique that works for us. That does not mean it's the only method that works. More isn't always better, tighter is often a problem and cleanliness is paramount.

Is it common practice to use a sealer on the gaskets?
I've always (not that many engines) installed them dry with good results. Maybe I've just been lucky with the sealing surfaces.

If something is used, should it be non-hardening or hardening?
