[Healeys] Is this 100 head warped??

[T+ B Willig]

Hello,

I was facing the typical problem of a blown head gasket since last week
(overheating, emulsified engine oil), so I decided to remove the new DW alu
head again. After cleaning the mating surface, I checked it with a
straightedge. Between the second and the third cylinder there is a small gap
under the straightedge were I can pass a 002 (0,05mm) feeler blade. Do you
think that I should send the head away for surface grinding, or is this
within tolerances?

Regards
