head and rocker arm torque specs

[lenordskowaisa]

I was wondering if any one had torque specs for the head and rocker arm. motor is a 6.9l and i am going with used head bolts. i am also going with the sequence of centre out and i am asuming about three rounds to tighten. I have seen at least three diferent specs for used bolts, 80lb, 85lb, and 95lb. if anyone can help on this would be much appreciated.

From my international book
"Cylinder Head Bolt (used) 80lbf-ft"
Step 1 40lbf-ft
Step 2 70lbf-ft
Step 3 80lbf-ft
Step 4 repeat Step 3

"Valve Lever Post Bolt(see note) 20lbf-ft"
NOTE-Rotate engine until timing mark (notch) is approximately 20 degrees before vertical position as viewed from the front of the engine, approximately 11:00, Tighten each pair of bolts down evenly.

thanks for the info, there is one other thing i forgot to post. I have recently rebiult the bottom end and was going to do heads as well but i am not able to now and am in desperate need to get this truck on the road. so i am putting old heads back on and will be starting in the next day or so. It pains me to only do half the job but i am stuck. How do I approach break in. I am new to diesel and don't know
