The first component is called a Hot Idle Compensator Valve (
HICV on your emissions diagram.)
When the engine is hot, the air/fuel mixture is richer than normal. The HICV opens slightly to let in a little bit of air into the intake and below the throttle valve to lean out the mixture at idle to compensate for the richer mixture.
The second component looks like a broken choke tube. Most Fords of this era used a
thermostatic choke with
electric assist. If that plate is bolted to the intake manifold, a tube was originally inserted in it to operate the choke. One end serves as a
fresh air tube that connects to the carburetor air horn, the other a
hot air tube that screws onto the choke assembly. The choke works in lockstep with the coolant temperature. As the coolant heats up, the tube also heats up and begins to open the choke. Full operating temperature = fully opened choke. (Small block engines used a chamber on the passenger's side exhaust manifold and uses the temperature of the exhaust to accomplish the same thing.)
You should also have a wire connecting the choke cap to the back of the alternator. That would be the electric assist. It only works above about 60 degrees to help the choke come off faster.
If the thermostatic choke isn't hooked up properly, you will have cold start problems if it temperatures are less than 60 degrees.
