I would also highly recommend Keith Pruyne (keith7932@verizon.net) - he was exceedingly helpful and patient with me when the carbs he rebuilt for me didn't initially work as well as I expected they would.
Where ever you get them done, give them as much information as you can about exactly how you plan to use them (- 4 into 4?, original air filter?), and exactly what look you are after (-polished/powder coated/cleaned original/etc..), and any known history of the carbs.
