What did ultrasonic readings show on a never-used Offenhauser 425 Flathead head?

The thickness measured right above the valves is written on the chambers. Most readings are close to half an inch, but one is .224. Steve does not know whether that is real or a limit of the ultrasonic method. He thinks the head is probably good as it is, but treats that spot as an area of caution if any of it were machined out.
