ARP makes a bolt set specifically for the RPM heads. I have them on my 360. I would not reuse the stock bolts. Something in the dark recesses of my memory is prompting me that there is an issue with them in this application.
I don't recommend re-using stock bolts also unless you know how many times that they've been torqued. If they have been torqued too many times, they can stretch and that can lead to premature failure...
