Older 1050 2 circuit T S R size to start with?

Its a older domi with the 1/4 inch tubes on top. It started as a 750 Domi and cut booster skirts off, enlarged angle passages and change to removable airbleeds on the Low air Bleed and set it to a factory 1050 2 circuit bleed, Works great at track and around pits but now he want to street it some so I thought this be a good Idea plus lower IFR if not already there. How about newer billet annular boosters with more holes?
