Well, I believe also that the standard helmets for all the films when the reveal wasn't being shot was a fairly snug fit to the actors. There's a ROTS clip showing Hayden being assisted getting it on and having to tie his hair back. I have a so-so Don Post Vader mask and it'll go on my head but it's a real snug fit. Vader's helmet is a pretty form fitting one where Stormies, Clones, Fetts are all just like a space safety hat of sorts so they're a bit larger.
The mask on the Sideshow Vader head could easily house a 1/6 human portrait behind it.
The mask and collar are pretty much perfect, it's really the dome that everyone's having questions about.
