I used explorer leaves on mine with 3" blocks and my home brew spring perches with some random leaves from a lifted pack acting like add a leaves as well as Belltech shackles and ended up with about 6" lift... If you are just going for 2" lift I would start with Explorer leaves (4 door used set can be had on craigslist for like $50, all you have to do is flip the center bolt...) and will give around 2" lift. If you want a little more from there go with chevy drop shackles, they'll give about 1" of lift.
I wouldn't recommend a bunch of blocks, with my setup I have a LOT of axle wrap and it's the equivalent of about 3.5" of blocks, and I did a tractor pull with this setup once and did a bunch of damage... in the tune of twisting an axle tube, breaking the lock ring for the rear output bearing on the transfer case, bent and twisted the driveshaft, and pierced the radiator with the fan... that was an expensive lesson
