Don't do any work on the intake port, but you can do shortside radius and bowl work on both the intake and exhaust ports. The exhaust port should be polished as smooth as possible.

Imho, the short side on those heads are the worst of seen, nearly a 90 degree angle. They can be rounded and smoothed easily, just did a set for a dirt track car. The bowls can be opened up some as well. i wouldn't mess with any guide work if your seats are done already. A good multiangle valvejob and good valves help a lot.
