How to only raise front c20?

[chickenwing]

I've got a 72 c20 camper special. I would like to know how to raise just the front of the truck to even it out. I don't wanna play with the rear at all. I was thinking just taller springs and had heard of using some off of heavier trucks in the 67-72 year group. I really don't want to be bounced around any more than I allready am either. Thoughts, comments, suggestions, links appreciated.
