If you are going to head blast the valve cover, then yes remove the rivets. On mine the plate was reattached using epoxy at each riven location. I suppose you could re-riveted it. I would not use screws which might come loose and wreak havoc in the valve train
When I vapor honed mine I shot carb cleaner inside, used narrow brushes and compressed air and felt comfortable with it. If it was tumbled I would remove it.
