if they were strech bolt's of any kind, or nyloc's nuts, then i'd agree, change them.... but, they're what i'd assume to be steel bolt's...... they don't change weaken or change shame once torqued.
i can't imagine they're expensive.... if you can afford to wait the time out for them to arrive, then your call, but i wouldn't worry indearly about changing them...
i've recently changed my mates teg' clutch.... after having the box rebuilt by a mate who is chief tech' at honda who also said about being safe to re-use flywheel bolts.
no prob's about the part number!
Ps. ORC clutch's are apparently very nice clutch's to run... i'll be fitting one in mine eventually once i've got my "stack of parts" fitted... lol
