    Pattern to tighten header bolts?

    Hey guys, I'm about to do a long tube header install on my 02 WS6 but there really isn't much SPECIFIC info out there on the subject.

    All I need to know is, what pattern do I tighten the bolts down in and how much torque do I use to tighten them. I'm sure there is some order to the bolts (like outside bolts first, or inside bolts first, or one end to the other)

    last thing, should I be using anti seize on the bolts (stage 8) or on the sparkplugs when I change them?

    18 ft-lb, usually I will tighten inner to outer
    ( * * x * * * )
    ( * * * x * * )
    ( * x * * * * )

    ALWAYS use anti-sieze into aluminum if you are not using a sealant.

    This is for stock '98, probably the same:

    6-3-1-2-4-5

    Two passes, first 11 lb ft - final pass 18 lb ft

    Same basic idea, just spread the force around the flange.
