Standard dies are used on the skins since the rivet head interface is no different from any other part of the airplane (there isn't Proseal between the rivet head and skin). Otherwise you'd use "tank dies" everywhere. The deeper dies for the ribs are to create space for the Proseal between the rib and skin. I just finished my LH tank and had no issues with protruding rivets.
