When we purchase parts for our (over 45 year old engines) we must be aware that the parts must be checked before fitting. I have been in the motor trade for over 40 years, and one rule that should always be followed is to check the new gasket with the old.
If this had been done before the head was fitted the problem could have been cured before fitting, either by contacting the gasket manufacturer or simply punching a new hole.
