Welcome to 2CarPros.

Here are the torque specs and procedures. The sequence is listed in the picture I added.


Cylinder Head Bolt Tightening Sequence
Torque:
1st: 17.2 - 22.0 Nm (1.75 - 2.25 kgf-m, 12.7 - 16.2 ft. lbs.)
2nd: + 85° - 95°
3rd: + 85° - 90°

___________________________________

Note that the second and third time you go over them the above listed numbers are not ft/lbs. They are in degrees of turning.

Let me know it that helps or if you have other questions.

Take care,
Joe

Tighten the cylinder head bolts in two or three steps in the order shown to achieve a final torque of 76-81 Nm (56-60 ft. lbs.) There you go.
