I bought a set of thread-in repair studs. I'm just waiting for the 14mm x 2.0 tap to arrive from Amazon.
One of my long studs is loose and needs repair. To get the long studs out - are they just press fit thru the head into the top of the combustion chamber? Are they threaded? Do I need to yank or twist to get them out? |

They screw in. Many of them have broken off when tried to be removed. As seen in the top example shown here:
I would try double-nut and unscrew, or use a stud extractor tool.

I do not know how to fix this. All I can say is it all works fine for me with what I use, Firefox. |

| Piece of cake. Double nut unscrew for the long stud removal. The long studs just run thru the top of the head and screw into the base. Once out, I just had to tap the boss with a 14mm x 2.0 pitch tap. I didn’t even have to drill - the hole left by the original long stud was the perfect size for the tap. Ran the threads with some cutting fluid and the short-stud repair base threaded right in. Set those with some red loctite and called it good. |

Glad to hear it worked out so well.
I will say, if you change one rocker stud, you need to change the other one on the same head!

Yes.

Thank you!
Has anyone installed a set of "pull though" short studs yet? I bought a set but I am wondering if I should also get a set of "machine in" instead? |
been a while since your post but for whats its worth (and hopefully this may help someone in the future) i recently pulled the threads on the original cylinder 1 rocker arm stud. it was my first time dealing with something like this but i purchased a knurled pull through stud replacement kit here in the classifieds and i can say install was super easy and it is working great. in my opinion, the design makes way more sense anyways as the insert and bolt pull against one another opposed to being threaded in the same way like some of the screw in inserts that you have to drill and tap for. picture of the parts i used below...
