oh ya,  whats the proper way to test the head studs to see if they're holding torque? Thanks, Matt.

Put the head on the cylinder, install the head nuts and see if it will hold 20 ft-lbs of torque.  If the torque wrench stops rotating the nut when the wrench reaches 20 ft-lbs the threads in the cylinder should be good.    If the nut continues to  rotate when the torque wrench reaches 20 ft-lbs your threads are pulling or shearing in the cylinder.
