    Cylinder head torque

    Did I torque my head correctly?

    New bolts
    30 flbs then 120 degrees

    Is this correct?

    Torque screws according to following sequence.
    First torque to 40 N•m (30 lbf•in).
    Then tighten screws turning an additional 120° rotation
    with a torque angle gauge and finish tightening
    with a 90° rotation.

    When finished with the 90* torque you should be between 75-95 LB-FT.

    Totally agree ... I hate stretch bolts. They squeal, groan, complain ... I always think I am gonna snap one, scares me everytime I torque them.

    So then why not just torque them to 85?

    bingo. Use anti sieze and 85 ft-lbs for me. That other chit is too dependent on variables of thread machining beyond my control.

    i know there has to be a good reason for that but i have no idea what it is..unless they have a shortage of torque wrenches that go higher in austria.
