Dave, recall that the water pump does not "suck" the coolant up from your radiator below, but  it "pushes" the coolant through the block and then into the radiator and back up to your pump.  With that short a distance (Head) to overcome, I don't forsee any problem keeping the pump primed as long as you get the system filled with coolant.  One advantage of my "Plugs Up" installation is that it puts the pump lower (relative to the block and radiators) and so if there is any coolant I can pump it.
