How to replace intake bolts?

To keep from hijacking lecki6's thread I decided to start another... I didn't realize the magnum intake bolts are one time use bolts and on top of that I torqued them to LA torque specs!! (35 lb ft instead of 12!!!!) and from what I've read that can cause coolant leaks in the cylinders. So how would y'all recommend I replace the bolts? Pull one bolt and replace it with a new one at 12 lb ft and keep swapping one at a time till they're all swapped or buy new intake gaskets and just take the intake off and start over with new gaskets and bolts?
