Stripped threads on 317 cylinder head
Stripped threads on 317 cylinder head I was checking the pre load with the turns method on the intake #2 cylinder and noticed that the rocker bolt would not tighten.The threads in the head are stripped.The bolt is ok. I know I will have to remove the cylinder head to fix this problem.
My question is can that be tig welded and re-threaded? I have a lot of money in those heads and don't want to replace the one head.I assume that you can't install a helicoil on that because of the force.What do you guys think?

Helicoils are stronger than tapped holes.
I called a vette mechanic I know and he said the way too fix this is to remove the intake manifold and install a rag inside the intake port. The hump in the intake runner is ground down (ported heads).Drill it out and put in a helicoil.When I did this post I was in utter shock to put it bluntly.
The problem is some idiot I paid to do the top end over tightened all the rocker bolts and I had to use a breaker bar to get them loose.I don't trust these heads now. Thanks guys for your responses.
