Dont buy no name brand injector O rings, make sure they are Alliant/Motorcraft ones, the no name ones wont last. Use 620 Blue lock tite ( correct me if im wrong) and make sure the cup bores are clean of any old sealant. Tugly has a good (HOW TO thread) and as most say go to Riffraff and they can rent you the tool, i bought mine thru Innovated diesel performance or something like that and the tool has held up really good the 10+ times I have used it.
I would also recommend buying some M6 bolts that hold Riffraff's cup tools in place. They receive a good amount of stress when removing and installing cups. There's no telling how close they are to thier end of life. I had two break off in the head while I was doing my cups. Next time I will buy my own bolts so that I know I'm using a fresh set. Just my .02
jhl3,
Excellent write up and I agree with the Hot torque recommendations especially. The mighty vac does help with cylinder clean up. Tried to REP you for taking the time to type all of that out but I'm in rep jail. Good Job.

Just to clarify and prevent possible confusion, the only color that I have ever seen Loctite 620 come in is GREEN. Has it been changed to blue now?

^^^ What Clay said.
Luckily the bolts don't bottom out so I was able to back them out with a pick tool (it took me about an hour to figure that out and it was by blind luck).
The kit comes with 4 bolts so I was able to finish the job. When I told Clay he said not to worry about it, the bolts get old and he would replace them.
