Carb Question

[Fun Family Ford]

Hello,
I am in the process of putting my '71 f250 360 back on the road. In the process I noticed the choke tube had broken off at the manifold. I am going to repair that with a universal part, no problem.
However, I noticed that there are 2 similar holes in the manifold. Does it matter which one I put the choke tube in and what is the other hole for? I have seen pictures of other engines where this hole also has a hard tube coming from it but I don't know where it goes. Is it the same kit to replace it?
Also, my carb has a capped off tube above the choke toward the back (middle of pic). My thought is this is the end point for the second tube. Is this accurate? Is it ok to leave it capped off or should I replace the missing parts?
All help is appreciated.

so if you have a hot air choke, your going to have two lines in the exhaust manifold. one line comes from the air cleaner in some fashion ( filtered air) to the exhaust manifold, gets heated then leaves the exhaust manifold and goes to your thermostatic spring housing. The idea is you don't want a unfiltered air source since your choke air ends up getting pulled into the engine. You can look online to see which one is supposed to go where. But here is an example pic of where you hook up one of the tubes, in some fashion to filtered air, either air filter or a port on the carb above the venturi in the air horn somewhere.
