Torque is 85 ft/lbs of torque. Tighten the bolts starting in the center of the head and working your way out to the ends. Go very slowly and only tighten slightly each time you move from the center to the outside. You must pull the head down very slowly each time. Here is the sequence,

Since you didn't say which engine you have, I've pulled torque specs for 3 different engines. Also, since I can't include a diagram showing the relative locations of the numbered head-bolt locations, it would be a good idea for you to purchase a vehicle specific repair guide that will show this info.
Take particular note about the TTY (Torque to Yield) bolts used on 2 of the 3 engines shown. It is said that new head bolts MUST BE USED when head is replaced or re-installed to obtain the proper torque.
B2500 4 Cylinder
Torque sequence: --------- ' 10 6 2 4 8
' front ' ' ' 7 3 1 5 9 ' -----------Step 1: torque in sequence to 51
Ft/Lbs Step 2: torque again in sequence to 51 Ft/Lbs Step 3: final
tighten all bolts an additional 90 to 100 degrees recheck final
torque in sequence *** CAUTION ***engine uses Torque To Yield head
bolts (TTY) that permanently stretch during the initial installation.
New head bolts must be used when cylinder head is replaced or
re-installed to obtain proper torque.

B4000 4.0 6 Cylinder

' ' 6 4 2 8 ' --------- Step 1: torque cylinder head bolts in
sequence to 26 Ft/Lbs Step 2: torque cylinder head bolts to 56 Ft/Lbs
Step 3: turn cylinder head bolts in sequence an additional 90-degrees
recheck final torque in sequence *** CAUTION ***engine uses Torque To
Yield head bolts (TTY) that permanently stretch during the initial
installation. New head bolts must be used when cylinder head is
replaced or re-installed to obtain proper torque.
Good luck with this job!

Fig.: Cylinder head torque sequence - 6 -cylinder engine
Cylinder head torquing should proceed in three steps and in the
prescribed order. Tighten them first to 50-55 ft. lbs. (65-71 Nm), then
give them a second tightening to 60-65 ft. lbs. (78-84 Nm). The final
step is to 70-75 ft. lbs. (91-97 Nm), at which they should remain
