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?

Research helicoil thread repair kit. That might help.

Helicoil or thread insert. Shouldnt have to remove the head unless the hole runs into a coolant passage

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.
