to many variables to give you any sort of number ,compression ,bore size,cams, tuning etc . but yes head work is always worth it the gains are very noticable with tuning , if you have the money to get it done by a reputable person get it done , you wont regret it . also theres so many levels of port work that can be done that can be done its just impossiable to give a acurate guess , but a piece of advise if you get it done make sure the person flow benchs the head before and afer so you can see how much airflow they actually free'd up to determine if you got your moneys worth

A word of advice: Leave the combustion chamber alone, unless it's very, very mild work. Even very tiny differences in chamber volume between different cylinders can cause compression and power output differences, which can override any benefits from touching it in the first place.
