Bringing a fastener up to proper torque cannot be bad, magnesium or no magnesium. I retorqued mine two or three times, and they seem to be stable now. Those retorques were very minor. Maybe one lb/ft.

Also, I have been told that when studs pull from mag cases, then cylinder tops and cylinder head mating surfaces get beat up. When this happens, those surfaces are no longer flat. If you then try to timecert the case and reinstall the cylinders and heads, the curved shape of the mating surface will prevent a good seal, the parts (cylinder and cylinder head) will rock against each other and eventually loosen the head studs again. I am told that these nuts will continue to loosen until the mating surfaces are trued (flycut).
