I am always good for an opinion!
I think 18 Ga would be sufficient. For instance if you put the tray in the toaster oven and try and toast bread, the side on the tray does not toast. That is what you are looking for, a shield to reflect the heat. I like your idea of an arced form connecting at the A and B point, to separate the sealing nuts from the shield nuts is there enough stud so you can leave the nuts as they are on the manifold and run the shield onto them and use another nut on the stud to fasten the shield? If not, can you swap longer studs?
I would also suggest having the tail of the arced shield go well below the bottom of the steering gear, this would encourage cooler air to chimney up the shield and help keep it cool enough that it will not radiate too much heat through to the master/steering box area.
The shield will rust quickly if you use cold rolled steel, the heat alone stops most paints from working. You could use powder coated porcelain, but that is a bit expensive. I suggest a brushed stainless, it does not stand out as too shiny so looks a bit more period. I used some on my cars and got it from Peavy Mart, they are just a tractor/farm supply company.
