All my Packards and Henney-Packards had heaters but if they did not come with it, the connections would have been plugged rather than looped around. Doing that makes quite a bit of coolant bypass the radiator.
Very true and both the head and pump ports had a 3/8 NPT pipe plug in the opening if there was no heater. If there is a heater Ross has mentioned several times that if you bypass the heater -- even temporarily -- with a loop of hose it needs to be plugged to prevent a considerable amount of coolant from having a path around the radiator. He has suggested a wooden plug or a marble be inserted in the hose. Just make sure whatever is inserted cannot fit thru the nipple on the head or water pump so it can end up in the engine.
