@ivanbendana let's start with the 3.7.

NOTE: The cylinder head bolts are tightened using an angle torque procedure, however, the bolts are not a torque-to-yield design.
(6) Tighten the bolts in sequence using the following steps and torque values:
† Step 1: Tighten bolts 1–8, 27 N·m (20 ft. lbs.).
† Step 2: Verify that bolts 1–8, all reached 27 N·m (20 ft. lbs.), by repeating step-1 without loosening the bolts. Tighten bolts 9 thru 12 to 14 N·m (10 ft. lbs.).
† Step 3: Tighten bolts 1–8, 90 degrees (Fig. 32).

Let us know what get's confusing on this.
