    Nick on cam journal - problem? Fix?

    As I got around to disassembling the 'new' cylinder head given the current state of the cylinder head that's on the bike, I found this nick on the cam journal near the cylinder 1 exhaust. There was no issues on the cam itself, and it seems like it is around 0.5mm deep. Thoughts?

      Looks like a casting flaw ( air pocket ) which was revealed when the journal was bored.
      Won't be a problem so leave it as is.

          Not worth bothering about.

              I can breathe now. Burque73 looks like nothing to worry about!

                  Thanks zed1015 and Grimly. Are there any checks that I can do to give you both more confidence before I close it all up?

                      Check the hole has a bottom.

                          I hate the thought of sending unusable stuff to people.
