Yes, the extra 2" gives "tire clearence" exactly the same as suspension lift would. "Ground clearence" at the frame/transfer case is not the same though.
If it is mostly street driven, this won't matter much though. Body lifting is fairly easy, especially compared to suspension lifting. The directions are very complete and easy to follow, the only thing that may cause a snag is that not everyone has a welder.... You will need to cut and weld in a spacer in your transmission linkage, either shifter or clutch, depending upon which you have.

The biggest problem you are going to have, especially if you go the extra lift and 37" tires....is gearing. An '84 model truck with a 305 is most likely a 700r4 and way too high of a gear ratio already. Many had 2.73s, and I have seen as high as 2.56. This is a complete dud with bigger tires, a nearly un-drivable slug.
Gear changing is not a budget minded thing and of course it's worse with a 4x4 because you have 2 axles to deal with. Re-gearing can cost more than the tires and lift together.
