That is some good technical support from the collective
I put the popcorn away for the moment.
Nice pics!
SuperPerformance base gaskets are the best
What happened:
The car ran normal before the center and rear carb came off.
Carbs get reinstalled and the idle is high.
Vacuum leaks usually mean poor idle

Start here
Be sure the distributor is not loose-see if it turns - if that's it stop and fix.
Warm up the engine to operating temp
Shut it off
Be sure the idle mixture screws are at least 1 turn out ccw
Disconnect the throttle cable
Remove the rods from the both outboard carbs - relax nothing is going to happen.
Be sure you leave ithe outboards in the closed position
Be sure to secure the rod from interfering with anything.
Be sure to actuate the outboard carb to be sure the throttle blades come to rest
Lock out the choke.
Turn idle adj screw CCW till it has no contact with the throttle blades

Check the float levels -Trickle out the ctr, just below on the outboards

Try starting the car by just turning the key [ btw a properly tuned car would start right up] If it does not run -it should not run - set the idle screw 1 turn in CW. It should start and run. Work backwards to putting everything in it's place.
No go over to the lift off hood playground where a decent version of the six pak tuning guide is and set the carbs up properly.

If it runs away like before: wiggle each outboard throttle blade while it's running.
