My biggest concern was the baseplate, since I've seen them warped before. I also found out that, even though Holley still sells the carburetor new, the 1848 baseplate cannot be purchased. A replacement is no where to be found. They use a 1.5" throttle bore, which is smaller than most other 4bbls (besides the 390cfm).
Fortunately, it was perfectly flat.
