While this thought/idea may not play out accurate, perhaps a computer sym like Desk Top Dyno could be helpful in at least show what could happen with a different cam. If anything, it could be a helpful tool in showing what is possible/probable.
They may help to show trends, but the more I used even a fairly high-end simulation program, the less I came to expect results that reflected the real world (at least compared to my experiences).
Have there not been published reports on flow balances between the ports and suggested cam specs for such balance
Well... there have been lots of magazine articles that attempt to simplify things to that level, but the reality is it's not that cut-n-dry. There are too many other variables that influence things (e.g. CR, RPM range), which is why IMO it's better to work with someone who is familiar with the type of engine & combination you have.
