1956 Thunderbird runs hot / overheating

Cspidy, what is a "double water pump?"
For clarity,
The original water pump only had pump blades on the forward side of the pump.
There were no pump blades in the spacer side as ilistrated in Doug’s post.

I was still having an overheating problem at idle on my 57 with the dual/high output pump installed.
After installing the spacer mine doesn’t increase in temperature while idling.
