Sir,
How deep is the damage/nicks? I would almost run them over to your local machine shop to have them take a look. Not sure if Indy cylinder heads still does repairs but they are a good choice and I would give them a call also.

Champion does a good job with repairing aluminum cylinder heads- they repaired mine within 5 business day before BG last year but charged an expedite fee $200.00 in-order to get them repair so fast. Make sure that William at champion is your point of contact- a really nice guy.
