Just know that it needs to be the correct type stud there, or it will never seal properly. There is a "bump" on the stud that separates the threads that go into the head from the threads on the outside of the stud. That "bump" is key to helping the stud seal that hole. Many people have used bolts and almost without fail they have a leak there, however small. I also use red high temp RTV to seal the threads. Regular teflon type thread sealer cannot stand the temperature and will dry out. I don't care how high the label says it will go.
