If you are repairing the engine to this level, a bottom or top rebuild, you should already have a chiltons. If not, what are you doing?! These specifications along with many necessary others should be in your repair manual unless you are just gathering this information for fun. Sorry about the lecture, but if you don't have torque specs for this, what else do you not have. Not only do you need the torque specs but each head bold needs to be torqued in a certain sequence as well. Head bolts are torqued in specific order gradually bringing the cast iron head to specification over three torque sessions.

for cylinder head the torque is : step 1 55 ft-lb, step 2 65 ft-lb, step 3 85 ft-lb. Rocker arm stud nut or bolt is 17 to 23 ft-lb. and valve cover bolt 72 to 108 in-lb.

For 1988-1995 4.3L,5.0L and 5.7L intake manifold bolts are torqued to 35ft.lbs.Start with center bolts on each side moving out finishing with the bolts in the front of the motor and the back

Torque to yeild bolts need to be replaced whenever the head comes off.....Long bolts are 46 ft lbs. and the turn 90 degrees (1/4 turn) short bolts are 43 ft. lbs. and then 90

1. Tighten the cylinder head bolts a little at a time, in the sequence shown. Tighten the bolts in three stages:
   • First pass: 25 ft. lbs. (34 Nm)
   • Second pass: 45 ft. lbs. (61 Nm)
   • Final pass: 65 ft. lbs. (90 Nm)

scroll down to about half way down the page , there is step by step procedure for the 1994 5.7 L head installation and torque and tightening sequence . handy dandy site . cheers .

The haynes book is not recommended since there are numerous mistakes and they still will not update. One of the biggest is the firing order.

The factory service manual is the only way to go.

Head bolts - 46 - 50.5 lbs (there is an order sequence for the bolts)

Intake & exhuast manifolds- 13.5 - 20 lbs

Flywheel - 41.5 - 47 lbs

Clutch cover - 13.5 - 20 lbs

Head bolt torque is 65 ft lbs, use the below sequence, go over bolts 3x to reach final torque (not all at once to 65)

13 5 2 10
front of engine 17 9 1 6 14
16 12 8 4 3 7 11 15
good luck!
