just have to wonder what else they missed in their magnaflux? I'm not so sure I would want that shop to do any more work for me. I'm not certain of the condition of your head, but often pinhole leaks come from severe rusting on the OTHER side of whatever has the pinhole leak. (I used to work on ships, I have seen a lot of rust, not real romantic I know, but hey....)fortunately these heads aren't really hard to come by.
