I had to go to the GM dealer to get the correct sequence and torque for mine, but my son has the specs right now. You do start out with 22Ft.Lbs first round, but the second and third rounds you will need a Degree Tool for this 2001 the Model, so be carful about where you get your info. The specs have changed on the later models. Also GM recommends that you replace the Head Bolts with new ones for this Model.
