There is a spec in the rebuild kit for measuring the distance between the float and the surface of the fuel bowl while inverted. Generically this laves the float surface level with the top of the fuel bowl while inverted, but there is a range of measurements (15/64"-1/2") by carb number. There is also a measurement for the secondary float that isn't always the same as the primary setting.
Holley 4160 carbs are a breeze to rebuild as long as you follow the instructions completely.
