Just to clarify, I said the OE screws were made if CrAp but assumed any studs would be stainless. Currently I am using ceramic anti seize and have been removing the headers more than anticipated.
I had two screws fall out at the last DE at OE torque spec which set me to thinking. So far no problems with broken screws but everyone I know has had to drill a few out.
