/6 to 5.9 magnum questions

Hello everyone, after browsing around endlessly as a gues on here i decided to create an account and ask some questions i have.

Going to be swapping out my slant 6 in my 72 scamp for a 5.9 magnum. Im hoping to get an engine in the next couple weeks and start gathering everything needed for my swap.

So i plan on running a carborated v belt system. I know mostly everything i need to get for the swap (thanks to FABO)

My biggest question right now is exhaust manifolds. Im doing this on a budget so TTI and dougs headers are off the table for now. I looked into the summit G9040 headers but not sure i want to take on that headache. So i read a few posts regarding using magnum manifolds. Can somebody explain which magnum manifolds i would need to look for for both Passenger and drivers side. And yes i am planning on keeping my power steering

Will my slant 6 power steering pump work on the 5.9?

Thanks in advance!!!
