12-16 thou gap and 34-36degree dwell angle for HR.
The meter needs a dwell setting or scale. Otherwise it won't measure it with meaningful readings.

Monte Solaro is the highest point on the island of Capri.
Dwell is reduced.
With points or mechanical-breaker style ignition, the air gap of the points is too wide. This is usually because of wear on the contacts or maladjustment. It's indicative of the amount of time the points are closed through the rotation of the distributor. Usually measured in degrees. High dwell - Point gap is too small, the contacts aren't opening as far, later and for less time. Low dwell - Point gap is too large, the contacts are opening wider, sooner and staying open longer. When given a range value for dwell, adjust for the low value and this will allow the point gap to wear through the acceptable range before the next adjustment. Point gap should decrease as wear on the cam follower occurs, increasing dwell angle.

Setting dwell angel and setting point gap accomplish the same thing. On my 64-1/2 Mustang I have to remove the distributor cap and loosen the set screw on the points. Place a screw driver in the slot for adjusting and twist until the gap between the points is correct. The cam on your distributor shaft must be aligned with the nub on the points. This achieves the Maximum Gap your points can achieve. It also determines your maximum Dwell angle (Angle is nub- points pivot - points tip). Tighten set screw when gap is correct and check for accuracy. Withthe car running and a dwell meter connected you can confirm proper dwell angle. Some cars have an adjusting screw external to the distributor cap so you can adjust using a dwell meter while the car is running.
