Cracked Holley/ carb rebuilders

I was adjusting the timing and points dwell today and noticed my carb body is cracked and damp with fuel. Is this a common problem with Holley 1920s?

I was planning to rebuild a holley 2280 to put on the 2 barrel intake I have. I also have a carter 2 bbl I picked up cheap to use as a core. What rebuild places are you all using if you are sending carbs out?
