For the injectors, in '03 the spec was 24 ft-lbs, later they increased it to 26 ft-lbs, and most builders recommend 28 ft-lbs to ensure the copper washer seals well. Make sure the bolt holes are clean and free of oil as this can affect the torque.
The rail bolts are 8 ft-lbs (96 in-lbs) for my '03, and your '04 should be the same. There is a sequence to tighten them in, here's the diagram from my service manual:
Tightening those oil rail bolts made me very nervous, being aluminum, be very sure of your torque wrench accuracy. Also, I just did 26 ft-lbs on the injector bolts, since that was the higher of the two factory specs and I didn't want to break anything. Good luck!
Driver or passenger side? I did both, and if I recall I couldn't get the torque wrench in on the lower passenger side so I used a box end wrench and did them by hand, comparing with another bolt I had torqued to about 85% of spec.
I didn't bother cleaning out the injector bores, I was concerned about knocking pieces of crap loose in there that could interfere with a seal, so unless you have the cleaning brushes and do it really well I wouldn't do it. Most builders use clean engine oil or ATF to lube the new o-rings, I used clean motor oil.
Not that I know of. I have smaller wire brushes that I put into a drill bit extention that goes into m 90 degree angle grinder. I put it odwn there, give it a few turns, spray some BG carbon cleana nd wipe it clean with rag and screwdriver. Than I either use my Blue-Point vacuum and suck the cyliner or blow it out with blowgun... Usually both. I then take snap-on camera down bores to make sure we all good... and pick up some STP Oil Treatment... Its thick as #### and it great for seals
I've probably spent more time reading and learning than hands-on with the truck. I believe I have it narrowed down but now the parts get a little more expensive to just start throwing at it.

I was reading an earlier discussion regarding smoking (white, smells like mostly diesel) at lower RPMs and clearing up as RPMs increase.. My truck does this. I haven't had it diagnosed yet but was hoping to get some feedback before I drop a ton of $$$ on diagnostics. It has been studded and...
I have a 07 F350 that has a strange noise only when slowing down, it has a growling noise from the front of the truck it seemed to start after the hubs where locked in. I unlocked the hubs, now it happens all the time when slowing down and now there is a slight vibration when braking along with...
My original starter on my '06 6.0 was getting weak. Bought this new starter with great reviews and installed it, truck cranks over very fast and starts awesome. However, more times than not theres a quick grinding as soon as the truck fires and I let off the key. The starter is supposed to be...
So I have 3 injectors on the pass side allowing air to pass horrible during ICP leak test. I pulled the rail and put in Alliant Nipple cup seals. No help. I pulled the rail again and put in new Alliant seals on all 4 injectors top O rings that the nipple cup plugs into. Same result. Of course...
