Holley offers jets up to #110.
I'd keep jetting before swapping air bleeds.
My experience has been that the air bleed is used more when you're looking to change the shape of the fuel curve( or when the jetting is grossly off, which often means its really the wrong carb).
But, they are easy to change and also easily reversible.
This only works if you're in the ballpark w/bleeds to begin with. My 1050 hp came w/71 idle and 37 hi speed bleeds so the idles were close but 37's are WAY too big for hi speeds and thats why I too needed 99 jets to get it better but not right. Now I'm at 70 idle and 28 highs w/82 and 92 jets w/a nice fuel CURVE not just jet it till wfo is good cos anyone can do that........
