Hi jeep 4.7 v8, I need to reinstall my heads of the motor and need to know how much torque they require and the sequence of the bolts?

Hello,

Tighten the bolts in sequence (Fig. 56) using the following steps and torque values:
Step 1: Tighten bolts 1-10, 20 Nm (15 ft. lbs.) .
Step 2: Tighten bolts 1-10, 47 Nm (35 ft. lbs.) . Tighten bolts 11-14, 25 Nm (18 ft. lbs.)
Step 3: Tighten bolts 1-10, 90 degrees. Tighten bolts 11-14, 30 Nm (22 ft. lbs.)

Here is a video on how to use a torque wrench.
