Points from my experience doing the job:
1) get a degree wheel for torquing head bolts
2) clean block threads. I used an old head bolt and cut two vertical grooves in it, deburred it and then cleaned out the threads. Amazing what crap come out! I then used crc to get them really clean
3) Buy NEW head bolts... amazing how much torque you put on when tightening, cant imagine how anyone would reuse them. I could actually see the bolt deformation when I had them out.
4) Injectors - particularly number 3 can get stuck. I used plenty of diesel/brake clean/wd40 - to try and get them a little lubed before trying to screw them out. On my old head, one of the injectors was completely stuck and ripped the lowe case off the injector, leaving it in the hole. Check to make sure they all come out complete
5) Take your time, make sure you have everything in hand (tools, components etc) - cant stress this enough. Rushing a job like this isnt a good idea!
6) Do an oil/filter change after the job
Lots of info on AULRO, especially from mechanics like justinc. All the best.
