Quick search (for '39 style Ford brakes):
The correct adjustment with new shoes is to adjust the anchor cams by starting out with the dots facing each other and the adjustment cams (upper bolts) at a minimum. Have someone apply pressure to the brake pedal and hold it. Using a small wrench, turn the dot on the rear anchor down until you feel the brake shoe touch the drum. Repeat the operation for the front shoe. Usually it takes very little movement to get the anchor set correctly.
After you have adjusted the anchor cams, you can adjust the shoes with the upper bolts for minimum clearance to the drum. This is the adjustment that you will do every few thousand miles as the shoes wear.
