So please let me make sure I understand... the 790 cannot benefit from improved/upgraded cams, as the current cams are... "very good" if not "perfect"?



I don't know that the 790 cams are perfect, but they are much better than the 865. In fact, there have been reports of substantial power gains from installing 790 cams in the 865 engine. Since the stock cams are really good for normal street riding, it would be hard to improve on them except by going to a custom cam grinder and getting a special profile specifically designed for your purpose, drag racing, road racing, dirt track or whatever.
