I decided that instead of capping two of the vacuum sources, I would just run a hose from one to the other... That can't hurt anything, can it?

k, you may be sucking gas fumes into the oil filler neck, i think i tried that and it didn't work at all.
the hose thats hooked into your carb(top left), run it too the large vacumm source under the carb beside the shutter valve.(its visible in moses pic, under the bolt on the linkage side)
pull the line that goes from the rear iron to the firewall and plug the opening in the rear iron, then run that line to the opening on the top of the carb. put a T fitting in that line and run the other side of the T fitting to the the clean air side of the airbox. that should work, just make sure the oil filler cap is closed tightly, because the car will not run if its open. i'm gonna attach a couple pics of my setup for reference
hopefully this helps
edit: the one vacuum source on the carb is open cause i, just pulled the choke off andhaven't had time to go get more vacuum caps

Let me chew on this and I'll see if I can come up with anything. I would offer you some pics of my vacuum line routing, but I just put my stock carb back on for a bit and its running funny (might have messed something up, switching back and forth). I would hate to give you a bad example right now. In the mean time though, go get a fresh set of plugs and try it again (leading only if you like). Just read another thread about fouled plugs looking fine.

Hookay. That's what I get from stepping away from the forum for a few days. 
So yeah, the picture I posted is of a '79 model year engine, but I am running an '83 now, so I have some experience with the later engines as well.
First off, your dizzy connection looks fine. Second, cap the vacuum sources, rather than loop them. Some of those nipples aren't vacuum sources full time, so looping two together could possibly bork up the works. On your intake manifold, there should be a hard rubber cap over a largish vacuum port kinda in the area of the shutter valve. I used that port to plumb my PCV into the manifold. You seem to have your PCV plumbed into the aircleaner, which won't do much. Also, I'm using a '79 aircleaner which has the charcoal canister integrated into the lid, so my venting setup isn't the same as yours. Make sure that you've got the carb vent, which is the large nipple right next to the fuel inlet and return on the carb, plumbed into the charcoal canister. Same goes for the fuel vent line that is circled on my picture. The port on the iron should go to a fresh air source. I've got mine plumbed into the air cleaner, which was convienient. Other than that, make sure that the round electrical connector that I circled is grounded to the engine and that all unused nipples on the carb base are capped.
Edit: I'll see if I can get some digi pics of my new setup, since it will be slightly more applicable than the pics I've got now. I'm still using the '79 carb, but with the '83 manifold and engine so I've got a bit of a frankenstien setup going on.
I really wanted to retain the '79 manifold, but no one near me wanted to weld on the manifold in order to block the ACV port on the engine, so I was stuck with the shutter valved goodness of the '83 manifold. The main differences in the carb is that the altitude compensator is in a different spot, but since I'm not using that, the rest should be similar enough to get you going.

Could you give an update? I'm working on mine as we speak and I have an amazingly high idle of 3000 and occasionally 4000.
I think it is because my ACV block off might not have the tightest seal since I didn't have short enough bolts, so I just cut some long ones, and I don't have vice grips so I couldn't take out my long stud.
