Just read past posts regarding heater control valves, which I may need. But first there is a problem with getting water to the existing control valve to see if it works. My '54 Kaiser has a manual valve on the rear of the engine head, which I've turned open and closed several times after the engine has warmed up, but no water is going through that valve to the heater control valve as evidenced by disconnecting the hose at the heater control valve. Does this mean the valve on the engine is probably bad or is there another thing to check. Also while checking things the only heater hose getting hot is the one running over the top back of the engine (possibly hot due to engine heat), which further indicates water is not running through the lines.
