I have always drilled the head off when this happens. Seen it happen a few times. Wasnt an uncommon occurance back when Toyota had the HG TSB/recall on certain V6's.

This is one of those cases where a hammer is actually the appropriate tool. Once the ARPs go on, there will be no more messing with hex heads!
