Setting Float Height CB750

Bike is 74 CB750 w/ Keihin 657A carbs. I've looked around about where to measure float height on the carb body, and found you measure from the lip, not inside where the bowl gasket sits. Just took my carbs out to adjust float height after making my gauge and am looking for a bit of specification. From the picture below, do I place my gauge on lip A or lip B? Difference between the lips is 1mm.
