    Depending what engine you have will depend if you need to replace them or not.

    If you do its because they are stretch bolts and stretch (Clue is in the name) so wont torque up correctly without the risk of shearing them.
    The truth is always the truth even if you haven't realised it yet...

    only 80p each or so at Autovaux so not worth running the risk

    iirc Vxl were about £4 each or something daft like that

    Given what they are responsible for, I'd not even debate re-using them, stretch bolts or not.

    You are best to use new ones but the old ones can be reused if they fall within the reusable tolerances.
    Check with either Vauxhall or autodata as to the reusable length of the bolts. If the bolts have stretched too much, they will bottom out before tightening.
    I would personally just use new ones.
