I ruined a 2.0 head. It had a stripped helicoil on an exhaust stud. I drilled it over size and tapped it for an insert. I don't think I tapped deep enough and I broke the exhaust stud boss.
Now the only option is a new head. And that really means 2 new heads if I do things how they should be done. If I could find a good used 2.0 head, I would use it. But I have to assume any used 2.0 head has issues. At least that's how I would play the odds.
Worst part is, I was planning on selling this car to focus on another 914 project. I didn't want this car to become a project. Maybe I will offer it "as is", with full disclosure of the problem. Sucks, but I try to remember some people have real problems.
Heads can be welded
That can be repaired.
I recently had some 912 heads repaired (cracks at studs, missing material at the exhaust ports and broken fins) ...
Before:
After:
... wasn't too expensive either.
Who will do the repair? I'm pretty sure Len wouldn't touch it.
Actually I will. A screwed up ex stud boss by itself is not a killer. If otherwise the casting is in good condition we can rock on. I routinely weld in new bosses for remachining. If your interested in what knocks a head out of consideration for my services read this.
