Some of the cooling ports are blocked by the gasket.

To be fair the thread are only damaged for a few turns as the spark plug was on such an angle it wouldn't go any further.
How the frig they did it is beyond me as it is very easy to tell if something is cross threaded especially on one of the most visible plug holes!
