well. honestly never take anything to a machine shop. I would try and just clean it yourself.
Do that or get another head. I don't know if you can find a machine shop which will properly take care of that area. Maybe I am wrong though, good luck.
If you are unsure how to start, you can try rubbing it with some soap and water. Some kind of light degreaser. Don't spray it on to the head directly just wiping with a towel. Try to determine if the debris is really 'stuck' in the metal or not. Sometimes it will clean up without much effort. Other times... you might have to resort to rougher methods, polishing wheel on a dremel or something. Get creative but use low speeds, low force, lighter materials, like cotton cloth. Think polishing. Maybe try some aluminum polish. I've never had to do what you need to do before so i dont have an exact answer, but I do know that you had better ask what the machine shop intends to do before letting them do it and wasting your time.
