Silly me. I have taken the water pump off and will elongate the holes in the pump. Yes it is quite likely the head has been machined to cause this, no knocking when engine is turned over so ok..

Hi Paul,
Well done on solving the mystery, they must have taken a lot off that head unless it had been skimmed several times in its life.
