AndradaFX4

What's up all, so I'm trying to figure out what I'm going to do to get a little more clearance. I have a 2002 F150 Lariat Screw with the FX4 off road package. I'm looking to get a 2" lift all around since my truck sits about leveled as is, I want to see what people would suggest. For the front should I just crank my stock torsion keys, replace them with aftermarket and what kind, or if there is even another way. For the rear should I get an AAF or Blocks, any suggestion would be great, thanks.
