Got a call from TA

Just an item of interest. On close inspection I have discovered that the threads in my new TA-Rover heads for the exhaust and the intake were double tapped. In other words the machinist ran the taps in once, backed them out and then ran them in again and cut a second thread right down the middle of the first one. This obviously took all the meat out of the thread, weakening it, and means I will have to install helicoils in every one of those. Not at ALL what I was expecting. And I can't send them back because they were the bare heads and I have already finished them out with valves and springs.

That's a real bummer.
