Default Tapping longerons for f-794 A

Hey everyone,
Working on my rear fairings and DWG 44 says to tap longerons for a number 6 screw. Easy enough, my question is, do I counter sink the actual skin/longerons and dimple 794A, or do I C/S the 794A, meaning less will be removed from the longeron?
Thanks in advance
Brandon

I countersunk mine, which means there is a slight knife edge on the fuselage skin. The countersink penetrates the longeron slightly.
