The newer replacement bolts have the thread locker applied already. It is important to use the correct torque, even for boost. I wouldn't expect 9psi to be a problem for the intake gaskets.
GM has a 2nd revision, that puts metal tabs around the bolt hole near the coolant passage. This is to help prevent over torquing these bolts. Felpro has this revision as well for their plastic gaskets, but they still revised them again after that to give us the metal version.
