Are Head Studs Made Out of Pot Metal?

[Rockitdoc]

I wasn't aware that studs pulled out.

Apparently, fairly common.

Here's my experience with a pulled stud previously repaired with a heli coil. Had to have the whole lot ground out, welded & machined. There was so little material to one side of the two studs next to the cam chain tunnel I had the rear stud hole welded also.

What a feckin mess it was in

I wasn't aware that your studs pulled out.

Good luck with the repair-looking forward to seeing the completed project.

Oooh, that's ugly ...

Oooh, that's ugly ... 

The repair looks nicely done.  The original mess looks like a nightmare!
