The heater valve is located behind the dash above and to the right of the accelerator pedal. The heater core is right beside it. It is operated by a linkage to the slider on the heater control panel.
The heater valve is in line in the heater hose from the top back of the 350 engine about half way to where it enters the firewall to connect to the heater core. The valve has a steel wire control cable connected to the top of the valve control lever. It has two hose connections, one in from the engine and one out to the firewall core entry point. Trace your heater hoses and look for the metal valve with the spiral covered control wire.
