1.84's could work, but 1.94's could work just as well, perhaps a little better, when you have to do a VJ and buy new valves I would go with which ever is cheapest for this engine, a good VJ and some bowl work is going to make the biggest difference in the low lifts that we are talking about here. stepping up to a 1.94" valve would increase your curtian area by 5% and allow you more room to work the bowls with. It'd be an easy 5% gain, probably more.- that's only 15hp on this engine though.
