Late model Chevy & Isuzu NPR's have heavy duty power steering that can be adapted. The NPR stuff is solid but very pricey. I know because that's what I mounted onto my '46 1.5T school bus.
And if you have a 5.9 up front, it will be putting a whole lot more weight on the front end for the steering to deal with. Mine is just a 3.9 (4BT) but it weighs about 400 pounds more than the original engine. The 6 is heavier still. And that extra weight also needs to be addressed on the braking & suspension side as well.
