No, I have not. Which valve on that exploded picture is the boost valve? I would assume the bore diameter of all those valves is probably the same, there doesn't at first glance appear to be a difference in valve bore size, but I haven't totally disassembled anything in search of something like that. I remember in the days of working on cars in dealerships, running changes used to come along when engineers came upon a better way to do things. Sometimes a technical service bulletin would come out describing changes, sometimes not. I suspect the valve with the thin spool about 2/3rds of the way into it, and the varied spacing between two of the valves near the center of the valve could be because of a running change. It would be imperative to be sure your linkage is perfectly adjusted and that the little pin that engages the manual valve isn't bent or the plate that it comes off of isn't damaged, either.
