So I pulled the header to replace the gasket and check out what had become of the missing stud. Of course the reason was that the prior owner had broken one off AND had tried to drill it out. So what I found was a gouged out hole app. 1/2 - 5/8" in diameter with this stud still deep inside and the head material below and to the right of the whole is gone. So do I have any options besides a new head? I put it back together in the meanwhile with a "remflex" crushable gasket and ultra copper high temp sealant.
