well my head gasket blew and i am putting the head back together and i want 2 know if anyone knows if with the 5s when u put th head back on if u should use new head bolts, and what r the torque specs for the head bolts. Thanks!

Those bolts are torque to yield so you cannot re-use them. Torque to yield means that you torque them to spec and then continue to turn them for a specific degree.
Specs: 36 ft/lbs + 90 degrees
The torque sequence is to start with the center two and then do a cross patern working your way outward.
