I used the torque method to set the injectors. Torque method and indicator method are quite different. (valve clearances as well) Have to do it on the firing order. 153624. Use the timing marks on accessory drive. ABC, should be. Turn the engine over by the accessory drive, its easiest. Way I did it was 1 do valves at .011 and .024 I believe, and 72 inch pounds for injectors (if not mistaken). Then same for 5 ect ect. Thats how I did mine and it runs very well.
As far as Jake, do it with engine running. as soon as you feel screw hit rocker, back it off turn and a half.
Hope it helps.
