SOURCE: Head bolt torque specs needed for 96 tbird 3.8

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:

  1. 20 Nm (15 lb-ft).
  1. 40 Nm (30 lb-ft).
  1. 50 Nm (37 lb-ft)
Loosen retaining bolts one at a time two to three revolutions and retighten as follows:

Long bolts:
  • Tighten to 40-50 Nm (30-37 lb-ft).
  • Rotate an additional 175-185 degrees.
  • Go to next bolt in sequence.
Short Bolts:
  • Tighten to 20-30 Nm (15-22 lb-ft).
  • Rotate an additional 175-185 degrees.
  • Go to next bolt in sequence.
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.

Always use new head bolts.

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: whats the torque specs on a 2001 ford focus 2.0

You need to buy the manual, because you also need to know the order in which to torque them.
http://www.car-stuff.com/mmparts/ford-focus/repair_manual.html
usually you start at the middle and circle outward.
But they can differ. Some cars you always need to put in new head bolts. Others are done in several stages. This is too critical to take chances on.
If you really can't afford $19 for a manual, go to the library and xerox the pages.
