Those are nice carbs. If you are running pump gas (I can’t remember if you are or aren‘t) I would certainly look into an annular booster that has a minimum of 16 holes and IMO 20 holes would be better.
Of course, I could be totally wrong on that so if I were you I would email or call Mark at Lightning Carbs and ask him what boosters he likes for your application. He makes his own boosters and that’s what I use.
