Upgrading springs to different stock replacements

[Smallz72project]

Im wanting to replace all the springs on my 84 so I have a fresh suspension. It used to be an old sheriffs truck. Currently the rear has a 4+1 spring pack and the front is just a 2 leaf pack. Goal is to keep the truck fairly stock, Im not really wanting to lift it but I wouldn't mind if it were a little taller so I can clear 33s with no issues, I also plan on towing my trailer and occasionally hauling heavier items. While looking at spring vendors I noticed that they offer a 6 plus 1 rear and even up to a 4 leaf front stock replacements. Question is if I were to go with a 6+1 in the rear for more weight in the rear what size should I go in the front. They offer a 2, 3, and 4 for the front. I was thinking 6+1 rear and 3 leaf front. I want to keep the truck somewhat level if not having a slight rake. Thanks in advance and keep on squaring!
