Therefore if you were to do some runner "work" you would have to re-work all the cast surfaces on the head (time and $$$).

Bill, like I said, racers are creative. Racers have got around it by glass beading or shot peening the whole cylinder head. One of the items I would suggest is making port templates based on available, over-the-counter gaskets. Mr. Gasket even has a set of templates based on their Ultra Seal line.
