New electric water pump??

Do you have a heater in that hotrod? If yes, it can be your new bypass. If no,are you running a thermostat? If no,all is good. If yes Id be inclined to rig a bypass up otherwise, until the stat opens all that water pressure deadheads at the stat and no water circulates. Would that be good for the heads? And if the stat fails closed....
Ive never run an engine without a bypass or a stat. Just saying.
