Hi Junkman, Re radiators, Alloy doesn't cool any better than the old copper brass radiators. Their coefficent of thermal conductivity is very similar.
Its just that alloy ones are lighter and cheaper because of the raw materials. Be very choosy about the brand as there is one Chinese made one that is a one year special. I think it appears here branded as a Fenix or something, but just rubbish.
Also I suggest you loose the flexi-lite metal fan as they are known to blow apart with age.(Metal fatigue.) There are plastic ones and OE ones that don't do that.
A shroud will buy you a lot of extra low speed cooling as it increases the fan efficiency about 10% for the most basic ones. A 63-4 impala drum one is simple and easy to mount and they are being repro-ed.
You may find something that works at a breakers yard but its also simple to make a fiberglass custom one.
What you tend to find with V8 conversions is the fan sits low on the radiator so its not in the optimum spot. The shroud wlll help with that if you find or make a tapered one.
What I like about the very basic Chevy one is it only aims to deal with the fan losses so doesn't cover the whole radiator which is a minus at speed. Also it looks easy to rework the sides to mount it where it needs to go relative to the fan.
Those headers will keep your feet nice and warm in winter, If you get issues, then you can wrap them where they pass under the floor.
If you haven't got the tank in have a think about putting a sealer product in it before its used.
Modern gass with alcohol added absorbs atmospheric moisture and is mildly corrosive so tanks corrode quicker.
I know POR15 make something but there will be other brands.
