Head/Mani stud stripped. How to fix???

[93jdmlaser]

Im sure someone has had this problem before. It is the 2cd stud on the lower pass. side. The stud threads in but just keeps spinning and wont get tight. I tried to JB weld it in but that didnt work. The weld did not bond to the head just the stud. How can I fix this. I dont want to have an exhaust leak. Is there a heli coil kit for this and is there any other way besides that to get it to stay tight in there. Someone help me out. Thanks

get a stud 1 size larger and drill / tap the hole for that stud.

Yea I went to the hardware store and picked up a 3/8in 24 tap and drilled out the hole and tapped it. Do you think I should just run a grade 8 3/8s bolt or cut the head off the bolt and make it a stud?
