Scott,
You probably have a local hot rod club or and independent V twin shop. Make contact, they'll know the machinist in your area that can build that up and rebore and tap the hole. Much cheaper than buying another head but not as fast. Either way you're going to have to pull the head. It's not so hard, patience and organization are the key elements to success.
But first just put in a new stud and gasket and find out if you have a leak. Better to ride the rest of the season with her a little wounded and then do the repair over the winter.
