Cylinder Head Bolts 3.8L

Step 1 37Ft/lbs (50N.m)

Step 2 Additional 120 Degrees

Step 3 (4 Center Bolts) Additional 30 Degrees

It's kind of weird, but this is the way it is listed in the service manual. Only the initial torque is given as a value, whereas the subsequent ones are by degrees of rotation.Hope this helps, good luck.
