head bolts ???

[spinnerbait]

I have a 1971 50hp evinrude that I blew the head gaskit on. I was wondering if I can reuse the head bolds and does the head need to be milled? I know on cars you cant reuse head bolts and anytime a head is pulled do to over heating you have to mill it. Any help would be great. Thanks

Can reuse head bolts, can take head to machine shop to have checked.
