Did you check the heater control valve? Bypass the valve to see if you get flow out of the heater core. If the valve is clogged or not working properly, you will not get flow through the core. I googled f350 heater parts and found this:
Control valve, f350 92-96 $28.72

I will check I know the hoses from the core are getting blisteringly hot..
