Hello, After my jeep dropped a valve seat last week, My new head will be here next week and my clymer manual doesn't have the torque specs!??? Anyway after a quick google search, im having a hard time believing what im seeing on the torque specs because mine were considerably tighter than what i have found.


Does this sound right???

Cylinder head bolts- 60 ft lb for the m11 bolts
19 ft lb for the m8 bolts

If anyone has them handy do you mind to share or post the list? Thanks so much!

Agree with sdg3205 you should get the FSM (Factory Service Manual) and even with a toque sequence you don't tighten the bolts down to full torque to start out. I would think they'd send you install instructions with your new/reman head(s) but maybe not.

In the meantime those couple specs you mentioned are correct and below is Chris Hager's list of torque specs.

Note that the specs on the far right of the chart are in "inch lbs". For the valve cover bolts 105 in.lbs divided by 12 equals 8.75 ft.lbs which isn't much.
