You don't wanna loose any keepers! And you won't need a PSC as the 6.1 runs perfect on SC, some guys have run it straight up on the factory pcm. I will post up pics of the tools you need, you may be able to get the damper back on without the insert threaded shaft with bearing but the miller insert is a must, my filed down crank edge is proof of that when i scratched the edge on home made insert back at cam 1. I would lend you my homemade valve tool but it has been used so many times and needs tweeking every 2nd or third spring but then again for the 30 i paid i,ve done 2 sets. There are some other small things to consider but will tell ya later (new damper, torque specs, procedure) I also have a PSC cam tuner i bought from Greg that may be available later but IMO you won't need it.
Just finished the valve seal and spring job on the truck and will post up pics later in that thread so have a look. Also you may find one of my ol cam threads or two just click on my name, stats, and threads started. Greg, Ken and all the other 03-05 Guys will help ya too!
