Whatever you do, don't follow the recommendation of llac_queen. They obviously have some learning left to do. No car or truck ever made has a cylinder head torque spec that low.

Here's the full procedure;
Install the bolts in sequence to 22 ft. lbs. (see pic in link) The bolts must then be tightened again in sequence in the following order:

a. Short length bolts: (11, 7, 3, 2, 6, 10) 55 degrees.
b. Medium length bolts: (12, 13) 65 degrees.
c. Long length bolts: (1, 4, 8, 5, 9) 75 degrees.

You can find a picture of the initial sequence here:

P.S. the manual recommends using thread sealant on the bolt threads. They probably go into a water jacket.
