Unfortunately, Unity doesn't allow for the OnGUI system's lineHeight variable to be modified.
However, you can do this easily when using Unity UI. If you rely on a Unity UI prefab for your Menu's Source, you'll be able to adjust the line height from the Text component. This method is the recommended one whenever you want to style your interface beyond what AC's Menu Manager provides.
