I don't know this from fact, but my experience has shown me that you don't need to. I have a six on a frame that has had both a four and an arty top on it at one time or another, and they all shot fine. Its my ultimate po'boys shooter. I have all three tops and one frame, and I take whatever upper I feel like shooting that day.
