    I was going to suggest this but I did t think it was that common.

    the overall cost of fixing this head would be more than a good second hand one.
    Turns out, far too much has been written about great men and not nearly enough about morons

      Yep - the plan is to shelve this motor now & just use the other one.

      This one can still be harvested for some spares if need be so isn't a complete bust....
      don't ask to ride my bike and i won't ask if i can shag your missus
