  2. Hello,

    As much as some people hate them, the haynes manuals are very good on this
    subject, apart from some not very clear advice on whether you need to use
    new 'stretch bolts', so it's better/safer to use new ones anyway.
    The job is not technically difficult, if you go at it steadily, in an
    organised manner, but you need to follow all procedures and tests
    meticulously, or damage can be done without you even knowing it until later
    on, a trustworthy assistant can be of benefit (the head is heavy).
    The need for the head/block to be skimmed/refaced should be considered
    especially if the engine severely overheated, and the redblocks are somewhat
    notorious for corrosion between the water journals and the cylinders.
    If you are doing the head, have you thought about changing the timing belt
    as well? Do the intake valve stem seals need renewing? It's a waste of
    effort not to really, when you have ready access to it!
    But where a manual or instruction says 'tighten to xxxft/lbs torque', then
    do just that; I thought I knew better once, then very expensively discovered
    I was wrong.

    Best wishes, Ken

    You should use new stretch bolts and also inspect the freeze plugs for
    corrosion. Change the front seals too. Plastiguage the cam keepers for wear
    and check for cracks. Line up the timing belts for the cam and interidate
    shaft and check that the distributor roter points to the no.1 plug
    wire.Sometimes the belt gets replaced without doing this and they just pull
    the distributor and reset it. The B230 is a non interferance engine so if
    you need to turn the crank or cam to line the marks uo it will not hurt
    anything. Good luck. BTW except for a Pinto, these are the easyest cars to
    work on.
