    Yes, they are TTY (Torque To Yield).
    Probably be an idea to replace the rocker bolts as well.

    Better to be safe than sorry, could get away with reusing them on a n/a engine but i wouldn't risk it with fi.

    Cast iron head and block. So not a huge amount of irregular expansion/ contraction. As long as the threads are clean as a whistle - I'd reuse them. They don't lose their elasticity.

    Its always good practice to replace head bolts, im not saying your motor will fail if you dont... but for the sake of $50 or so you may as well do a job properly.

    Re using TTY bolts is like pissing in the wind , can be done but makes a mess

    The bolt actually elongates permantly when torqued and as soon as they are loosened they are fatigued , re using them is not worth it
