Truck Repair: Cummins ISM valve adjustment, rocker support, torque specs

Question
I have a few questions that maby you could help me with please 1.when starting the valve adj proc. i have all the valve rockers loose and i set the timing mark to A does it matter where I start on either 1 or 6? Right now I have all of them loose 2. With the jake brake installed do i adj that on the same cyl as the rest of the valves and injectors? 3. I had to only replace 1 inj do I need to loosen the front rack and gauge between the rocker support and the rocker levers (.022)? 4. What is a rased face mark? this is all new to me being that i use to work on the older NTC motors And finialy in the book it gives two different torque specs for torquing the jam nut one for the use of a torque adapter and one with out. Being that i don't have a torque adapter i can just put a socket over it and torque it to the higher spec? Your help on this matter would be greatly appreciated. Thank-you for all your help

Answer
1:It does not matter which cyl you start with so long as it is the correct cyl for adjustment.2:You can adjust the jake after you asjust inj & valves.3:The only time you set rocker  clearance is when you remove them or loosen bolts.4: As far as the "raised Face",if it is for the valve adjustment,it is located on the frt cover at 12 o'clock position.
