I know that a picture is worth a thousand words but posting a picture on this site is a PITA. Here is a summary from the 2004 shop manual:

Lightly lubricate head bolts with engine oil and
install. Using the sequence shown in (Fig. 18),
tighten bolts in the following steps:
(a) Torque bolts to 70 N·m (52 ft. lbs.)
(b) Back off 360 degrees in sequence
(c) Torque bolts to 105 N·m (77 ft. lbs.)
(d) Re-check all bolts to 105 N·m (77 ft. lbs.)
(e) Tighten all bolts an additional 1⁄4 turn (90°)

The sequence they are referring to in "fig 18" is basically start in the middle of the head and work your way back and forth from one side of the head to the other from the center of the head out to the ends of the head. Do the center bolts, the 2nd bolts to the left, then the 2nd bolts to the right, then the 3rd bolts to the left, the 3rd bolts to the right, etc until you reach the ends of the head.
