I am going to get 2.055/1.6 valves and do the porting (cleanup the runners) myself. Merkel Racing in New York will do a 5-angle valve job, hog out the intake inserts, and backcut (30deg.) the valves for about $200 (dont have the exact prices with me)
From what they say, the 2.055 is the largest you can go.
