AutoZone can/will give you that data.
The bolts are torque-to-yield. Replace every time they are removed.
This is for '06, the only one I could find -

18 lb ft+60°+60°+60°+10°

NEW HEAD BOLTS ARE REQUIRED WHEN REPLACING THE HEAD OR HEAD GASKET.

Step 1: 18 lb.-ft.
Step 2: additional 60 degrees.
Step 3: additional 60 degrees.
Step 4: additional 60 degrees.
Step 5: additional 10 degrees.

Each step involves starting at the center two bolts of the head and alternately tightening in a criss-cross pattern, ending with the bolts on the outer edge of the head.
