Torque for tappets and cylinder head, and must bolts be replaced, after first time head removal.my initial problem was 2 manifold nuts broke off had to have it removed and new bolts fitted, now I'm replacing head and gaskets.

Head bolts are torque to yeild so you MUST use new bolts.
Tighten cylinder head retaining bolts in numerical sequence in three steps as follows:
Loosen retaining bolts one at a time two to three revolutions and retighten as follows:
Long bolts:
Short Bolts:
Here is a pic of the sequence

Here you go, I hope this is what you were looking for:
For 1987-94 models, the cylinder head bolts are tightened in 3 progressive steps. Tighten them in the proper sequence as follows:
Step 1: 50-55 ft. lbs. (68-75 Nm)
Step 2: 60-65 ft. lbs. (81-88 Nm)
Step 3: 70-85 ft. lbs. (95-115 Nm)
Let me know if I can assist you with anything else.
SOURCE: head bolt torque spec
Always use new head bolts.
1)tighten to 40ft/lbs
2)back off 1/2 turn
3)tighten back to 40ft/lbs
4)tighten an additional 90 degrees
5)tighten an additional 90 degrees.
SOURCE: need cylinder head gasket torque specs.
looks like there is special sequence to reassemble and tightening, a quick note replace any bolts that have two punch marks.tighten as follows: x x x x x 10 4 2 6 8 x x x x x 7 5 1 3 9 torque all down to 15 ft lbs torque to 30 ft lbs plus 90 degrees. Good luck!
SOURCE: what are the torque specs for the pinion nut and
Most pinion nuts don't have a published torque spec. they are to be tightened until the pinion requires a specified torque to spin with the wheels and brake drums removed. Often times, when a rebuild is not performed, it should be torqued to the same preload as before the work. autozone.com has alot of good repair info and diagrams.
