    Start from the middle and work your way out. :-*

    Also don't put too much Oil onto the Head Bolts, As you may Hydrolic 'em. - Use as little Oil as possible, Just enough to cover the Thread. ;)

    Bad, here's a low res pic I found. Jonathan is right; start in the middle and work outwards in a criss-cross pattern. Run them all down snug (a few ft-lbs or N-m), then torque them all to about 2/3 final value, then torque them all to final.

    The sequence is similar for any head.

    thanks all. like every other cruiser problem i've had. they always throw a spanner in the works.

    my head is in this general configuratio, front to the left
    (there are more bolts, but i can't be bothered doing them all,

    0 0 0 0 0 0
    0 0 0 0 0 0
    0 0 0 0 0 0 0

    But it's all good, i coerced the old guy at the toyota wrecker to draw me a diagram explaining the the correct procedure. i'll translate it up here if anyone's interested
