Now I basically just have these questions:

1. Does anyone know how different the AFM 1, 2, and 3 cams are? Like how much more aggresive is 3 compared to 2 and 1?
   Yes 3 is the more aggressive one, the rest are not worth it IMHO.
   
2. Does anyone know where to find any dyno numbers for each cam or what the general increase in HP and torque is? I looked everywhere and couldn't find anything and if I did, it was just the dreaded red x
   Look in the L99 dyno sticky and search there.
   
3. Do I need to replace the push rods? I figured I do but I just want to make sure...
   YES, with the correct length and you'll know what size when you choose the cam, the company will let you know what the correct length is with their cam (as long as you don't mill the heads)
   
4. Lastly, do I need to replace the springs or anything else in the valve train?

Of course you do, a set of Brian Tooley platinum springs, and do the comp trunnions upgrade along with a katech C5r timing chain and deleting the chain tensioner with an Ls2 dampner.

As always I love this forum and thanks for the help
