Head Gaskets...head bolts..

So I have to pull my heads to try to figure out if I have a blown head gasket. My question is, when reinstalling heads will I need to get new head bolts? Are they torque to yield bolts? Or can I reuse? Also are there any blind thread holes that I need to worry about? Its a gen 5 502..
