What to do with my suspension on 71 GMC

[Hibred]

Hi, guys bought a 71 GMC last summer, its a pretty truck, all done in a Harley theme, orange and black, originally from Arizona, has a 402, 400 turbo and near mint interior and has been lowered, now here is the part I could use some advice on. The lowering is a bit much if your not careful the headers can and will hit so would like to raise the front up a couple inches and now the rear is where I see the most problem to me, it has a leaf suspension that is under the axle, rides hard, what can be done with the rear. If I am going to raise the front with some different coils can the leafs be changed over to coils with a kit, which kit is best and how much would I be looking at, is it something I can do myself, I have a hoist. Throw some ideas and suggestions out there, thanks. Oh, one other thing, I would like to keep it reasonable as possible too.

I would change to mid length headers before I raised it up.
It sets good.
You can c-notch the rear to add more axle travel.
Pics of the actual suspension would help.
Most lowered leaf spring trucks never get the rear shock set up correctly to help with the ride. Most are layed over at a terrible angle.
You can make what you have ride good.
Please post more pics.
