Heater Coolant Restrictor
Well here is the pics I promised about what I found one day in my heater port on the drivers side head. The part is no longer available from Ford but this is what the demensions of the rubber restrictor. You can make it up and just push it into the brass fitting. You will need to remove it from the head to do this. I still haven't found out why its in this fitting either. Maybe for the west coast type trucks that don't need full flow to the heater.
