Holy smoke.
First picture. Red Manifold vacuum lines. One used to go to dizzy vacuum advance, but now since these carbs are different, the vacuum signal there is not useful. Green holes. if there are connected to the manifold, plug them!
Second picture, Big one of valve cover needs to go to the the air cleaner. Many people put a little k&N filter on it. Other nipples, ignore!
Third picture. That is the crank case vent and needs to have a PCV valve on the end, connected to the intake manifold so it has soemthing to suck on to, well, vent the crank case!
Forth picture green. The two ports look like bowl vents but I'm not a DGV guy. They need to be connected to the atmosphere. Again, should go to the air cleaner.
Fifth picture: No clue. Someone? What else in the thermo/dizzy harness?
sixth picture. That "thing" is a condensor. Connects to + side of the coil. Designed to keep ignition noise out of the radio. If your radio is quiet, ignore it.
You really need to study some here about SU carbs and how they hook up to their lines. It will show you why you have stuff disconnected and where it goes on SU's and what its needed for.
The only missing picture is you taking the DGV's off and getting proper SU's back on there!!!! Just my opinion.
