I guess you could get by with only doing one, as long as your are POSITIVE which head gasket it is. You would be kicking yourself if you had to do it a third time. FWIW, I originally put in ARP head bolts in July when I did the heads/cam. Blew a head gasket that same month, finally got around to replacing them a few weeks later, and I reused the ARP bolts. I haven't had any problems.
DISCLAIMER: I am in no way suggesting you reuse your ARP head bolts. I am just indicating that I did, and had no problems with it.
So if you do reuse them, and another gasket blows, don't blame me.
