I've got all the torque numbers wrote down...but I'm gonne guess right now (they are in the garage)
Once the new injector is in...you tighten down the injector to 44 in/lbs...the you tighten the feed tube retaining nut to 11 ft/lbs...then you go back and tighten the injector to 89 in/lbs...then you go back and tighten the feed tube retaining nut to 37ft/lbs (yea, its a pain in the ass)
The little nuts on top of the injector that hold the wires, those are 11 in/lbs. The rockers (I believe) are 27 ft/lbs (I will verify tomorrow once I get my sheet)
As far as your question on if there is anything special you need to do with the rockers...yes, there is. Look up "adjusting your valve lash". On the side of your valve cover there should be some specs that say "valve lash"... int (intake) .010 and exh (axhaust) .020 What this is is the distance between your rocker and the valve spring bridge. Once they are in spec, this will quit down your engine A LOT. It is a recomended maintanace item at 100,000 miles. And if this scares you...don't let it...honestly it took me 10 minutes to do this...was the easiest thing all day. I will find you the write up I used to do this...it made life simple.
Hope this helps man...PM me if your interested and I'll give you my cell and I can answer any questions you have when you go to do the install. I'll get the torque specs and write up for you when I get up...I just got home from work.
