    intake/exhaust torque specs on a 4.0L

    first let me say that this is one KICKASS design, and that it may be the most capable NEW rig out of the box, it is also the cheapest POS I have ever worked on, including the 87 sunbird 'vert I used to pimp (Ok maybe not that bad..)
    Anyway, I am replacing the header on "The Giant" and need to know the torque specs for the bolts on the intake/exhaust. Anyone have any idea, Butkiss said 80 ft/lbs. off the top of his head(seemed high to me) but a different site said 23 ft/lbs. for the old 4.2 motor, anyone know for sure? I also tried pirate but couldn't get the search part to work, if anyone else can get it let me know. Give me a call tonight (Friday) if you know, I would really appreciate it 214-732-1819 (This is Jimmy)
    JEEPS KICK ASS!!!

    This is hard to explain...

    If this is too hard I'll draw something...

    Bolt #s 1-5 and 8-11 should be torqued to 23 ft lbs
    Bolt #s 6 and 7 are 17 ft lbs

    **** it here's a drawing since it's too hard to explain

    this is also the order to torque the bolts in...
