    Re: 770 head torque spec

    The bolts are to be torqued in 3 steps to...

    Take your pic: In the head install procedure, they list 24-27 Ft-lbs.

    In the torque spec chart, they list 13.5-20 ft-lbs.

    Looking at values for the 1000cc engine, the 13.5-20 ft-lbs appears to be the right set.

    Since it is not stated specifically, one must assume these are "dry thread" values.

    Torque pattern is attached.
