Recent bought 1936 Club Sedan severe overheating???

Just bought the car. Overheats very quickly. I 5-6 minutes. Boils over. IR thermometer shows hotter in rear of engine. Engine runs great, starts, smooth. The middle eight engine. Not Super Eight.

I was suggested to pull front clip and remove large brass squarish tube from engine as may be clogged. Checked everything I can see, otherwise.

Ideas?
