Drop the oil pan before you remove the head, and fill the cooling system with plain water, not more antifreeze. The pan has to come off anyway to do a good cleanup. Pump a few pounds of air pressure into the radiator if necessary, and try to find where the leak is coming from. Removing the head first might actually hide the source of the leak.
