Use 2 passes to achieve final spec, & follow “helical” sequence each pass.

First pass (torque wrench): 22 ft/lbs

Final pass (angle wheel):

  1. Long bolts : 75 degrees
  2. Medium bolts : 65 degrees
  3. Short bolts : 55 degrees

Yup i need the same and everyone seems to think they are different size head bolts which is for the 4.3 prior to 2013, not for the lv3

59lbs 1st pass 90⁰ 2nd pass 70⁰ 3rd pass ? That's 211 lbs ft torque !
