I have an inlet temp gauge to monitor the engine temp.

bigd1101,
The size of a zero pressure cap is the same as the 4# cap and they both fit the Brassworks radiators.
A few guys commenting do not understand what radiator you have, I do. I have two pressurized systems with the radiator you name.
I am currently running a sealed (pressurized) Brassworks in my Phaeton with a 4# cap hidden under the hood. I have a Motometer on the car...as you say about your Quail, the Motometer is just for looks.
The second system is a Brassworks sealed system radiator but due to a low spot on my block, I can not hold coolant in one corner if I used a 4# cap. My temporary solution was to use a zero pressure cap on the under-hood opening.
I have used the pressurized system in my Phaeton for over 90,000 miles with no issues. I have used the zero pressure system in my '31 S/W Town Sedan for about 7,000 miles.
I currently have the engine out of the '31 S/W with the zero pressure cap to flatten the top of the block. I do plan to use a 4# cap when I put it back in the car.
Your plan to use the zero pressure cap and a reclaim tank will work. Obviously the reclaim tank should be vented to atmosphere.
Good Day!
