72 C10 LWB Springs Questions

[domano 68]

My new to me 72 C10 is going to need some new springs and shocks. I'd like to get the truck back to its original stance or even a bit higher. I might even put a big block in it one day in the future. So, instead of replacing with stock factory ride height springs, should I replace with big block springs and how much additional height would this provide? What type of springs could I go with in the rear to match the additional height of big block springs?

What is involved here (newbie). I know these things are under a lot of pressure. Are the rears easier than the fronts to remove and replace? Thanks in advance!
