Note that the 6 port has the latest closing ports of all rotaries. If you  will have both sets of the secondaries open together perhaps moving the closing  line of the upper port would be less than helpful.  
I didn't move the closing point at all on the side housings.  I would say that they are still at 40° ABDC.  I did move the closing in the intermediate housing up, but I think they are almost exactly even with the side housings.  I'll check.

6,000RPM is my target for cruising, so the stock is probably about optimum.
