I degree the stock cams in my 04/05 engines and will be doing the same with 09 engines I'm replacing the 04/05's with. At some point I posted how to reposition the stock gears so you can use them for the degree'ing.
This site Elgin cams http://www.elgincams.com/campaper.html
has a write up on cam timing that might help you to decide what changes to make.
Here is a picture of the cam gear which has been repositioned and marked.
