Imagine that the head bolts are numbered from left to right. Go 2-3-1-4 and set the wrench to 23 ft/pounds.

After repair job, temporarily install and tighten the two center (right and left) cylinder head bolts to 14 ft. lbs. (18 Nm).
Install the camshaft sprocket together with the timing chain onto the camshaft. Make sure that the marks made earlier, line up. If the chain will not stretch over the sprocket, the problem lies in the tensioner. Refer to the Timing Chain removal and installation procedure for the timing procedure, if necessary.
Install the cylinder head bolts. Note that two lengths are used. Tighten the bolts in sequence.
Tighten the bolts to 33 ft. lbs. (43 Nm)
Tighten the bolts to 47 ft. lbs. (61 Nm)
Tighten the bolts to 47 ft. lbs. (61 Nm)
Tighten the bolts to 55 ft. lbs. (71 Nm)
Tighten the bolts to 30 ft. lbs. (39 Nm)
Tighten the bolts to 44 ft. lbs. (57 Nm)
Tighten the bolts to 54-61 ft. lbs. (70-79 Nm)
To complete the installation, reverse the removal procedures. Adjust the valves to a preliminary COLD clearance of 0.2mm for the intake and 0.25mm for the exhaust. Operate the engine until it is at normal operating temperature, retighten the head bolts (loosen them slightly and retighten to the final torque figure) and adjust the valves to the HOT clearance specifications.

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.
B3000 3.0 6 Cylinder
Torque sequence ---------- ' 6 4 2 8 '
' ' ' 5 1 3 7 ' ---------- Step 1: torque to 59 Ft/Lbs Step 2: loosen
in sequence (1) full turn Step 3: torque to 41 Ft/Lbs Step 4: torque
to 73 Ft/Lbs
B4000 4.0 6 Cylinder
Torque sequence --------- ' 5 1 3 7 ' '
' ' 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!
