shackle flip, add a leafs, blocks
The shackle flip is possible, but how much lift you want will depend on the location of the shackle bracket on the frame and the length of the shackle, and wether or not you use a block, so there isn't gonna be a simple answer to this.
When I did my shackle flip, I was looking for 10 inches of lift. I kept the factory block, stuck in an Add-a-Leaf, and I had to install a 7" lowering shackle for a GM, flipped upside-down to raise the truck. I also lowered the front spring hanger about an inch on the frame.
From what I read here, you can follow the plans to build Mrpeal's shackle flip, remove the block and you won't gain any lift, or leave the block in and gain 4 inches of lift. Doing a shackle flip for only two inches of lift seems like alot of work, but if you can do it for nothing then try dropping the hanger on the frame and experiment with shackle length and removing or keeping the block. Shackles can be purchased in any length, but you'll have to buy shackles for GMs and you'll have to check out the lowrider shackles, remember that you'll be flipping the shackles so that shackles rated to lower a truck, will raise your truck when you flip the shackle.
Good luck
