Move to Minnesota. It will be hard to start that engine in the winter.
The intake manifold needs heat to help keep the fuel/air vaporized and moving down on down to the head.
The damper directs the heat from exhaust up to the bottom of the intake manifold.
When the spring heats up, it rotates the damper into the open position for normal run.

Here in the humid South, we have frigid days but nothing like the cold North.
Our prize AD trucks usually stay in the garage or carport.
We use the car or truck with air conditioning to defog our windshields so we can see out.
