Mark, a rough finish is fine. Some builders prefer it. My preference is to have the ports rough where fuel is in suspension and polished everywhere else. The finish is kind of irrelevant on the exhaust side since carbon will build up anyway. A polished finish is only relevent in racing applications where the motor is torn down frequently or where carbon does not deposit.

As far as programming, it seems that they are indeed proofing on your heads. Sounds like the fist time for that port size. If they have been successful in the past then there is not really much to worry about. There is not a great deal of difference between them all.
