Hello mooredavid42,

The Head bolt torque is as follows:

1. Tighten all bolt in the sequence shown in the image below to 22 ft. lbs.
2. Tighten all bolt in the sequence shown in the image below to 45 ft. lbs.
3. Check all bolt to verify they are torqued to 45 ft.lbs in the sequence shown below.
4. Tighten bolts in sequence:
a. Bolts 1-10 to 110 ft.lbs.
b. Bolt 11 to 100 ft. lbs.
c. Bolts 12-14 to 110 ft.lbs.

If you are reusing the head bolts carefully check the bolts for necked down threads.

You can find just about all of the torque specs that you should need here. Also you might want to order yourself a Chilton manual. They usually have all of the specs in the back of the book and throughout the different sections.
