I'm looking at an '03 cobra convertible that i may buy and had a question.
The left head just above the lower intake is painted a shade of ford blue.This seemed odd to me, is this normal? The car only has 15k on it. Any help would be greatly appreciated.

Yes this is normal when the head has been changed. The head was changed do to the tick which is caused by the the valve guide warping due to improper cooling passage. You should be just fine not all cars developed the tick.

The blue stripe is normal. It was thought that the blue strip meant the head was the revised non ticking head but it has come up on many forum that Ford used it to identify the left head. My 03 new from the factory had a blue striped head and it still developed the tick.
