Truck Repair: valve adjustment, screw out, valve clearance

Question
What should the valve clearance be on 98 model m11 celect,Do I need to adjust the injectors,this is my first overhead on m11,anything else I should know?  

Answer
On the Celect,you adjust valves & inj on same cyl.The mark A is now 1-6,B is 2-5, & C is 3-4.Valves are Int 0.014 & Exhaust is 0.027.The injector you hand tighten screw until injector plunger bottoms out.Back screw out 2 flats,ie turn corner of lock nut to align with the riviot in the rocker lever(pushtube side),then back out screw two "corners" then tighten the jam nut down.Adjust the Injector first,then the valves.
