Is there any external things to look for 78-80 Q-Jet?

I know a guy that has a massive amount of Q Jets. He's offered to give me one if he has it. I know the straight fuel inlet but is there any smoking gun features to look for going through his stash on a non CCC Q jet draw through? I read through the sticky but some of the links are dead
 
That castings are porous and will leak through the metal. There is no way to win the battle. They're good for concourse restorations and not much else.
 
I've never heard the porous thing before. My Q-jets are doing fine and many of the Buick 455 guys I race with use them. They are complicated, but good carbs. I've never seen them leak - the throttle shafts do wear/leak and need bushings sometimes.

The turbo V6 non-computer carb was 800 cfm. The primary venturis are larger. Google "quadrajet 750 vs 800".

Carb numbers are listed here:
