Eratic temp gauge

I'm running a 302 ford in my F1 with an edelbrock aluminum manifold, and a 12volt system
I had the gauge cluster updated with a runtz attached to each 6 volt gauge.
each was calibrated with new mopar senders.
gas (which is stock) amp and oil all work fine, but the temp will run normal needle in the center and at other times at the hot side, out side air temp doesn't seem to matter. when I shut if off after a trip and return later the temp always goes to the hot side once under way
wondering if the aluminum manifold has any thing to do with this.
I borrowed a laser and read the temp of the engine after a trip and it registered 170deg on the block and manifold.
This more of a nusiance than a problem as the engine doesn't overheat

Doc here,

Try purging the system of all air.

You may have a small air bubble stuck or cycling around the temp gauge.

A sender can not read air and as it passes and settles it will give erratic readings.

Check that first before going to the electrical.
