SET SCREW LOCK DOWN
To repair a set of heads that had been threaded and tapped for screw in studs, and where we could not use a shouldered hex stud or guides plates, I locked the studs in with set screws. Whoever had worked on these heads before had tapped the heads with a bad tap and the studs were loose in the holes. I removed the studs and setup the cylinder head in my head shop to drill the stud bosses on the intake side of the head. The holes were threaded and set screws were locked down on the reinstalled studs. They aren’t going anywhere now and this trick can be used to lock down any stud where you have access the the side of the stud boss or housing.
