I heard some cars have a problem with the driver side head and the only fix is to have Ford replace it.

yeah it was mentioned on horsepower tv. if the head was made before nov 02 it could have the prob, i know this for a fact because i have that episode on my tivo and kept that in mind when i was shoppin for mine

All 03/04 Cobras regardless of the date of manufacture either have the "head tick" or may have the "head tick" in the future. IMO it is nothing to worry about as I have not heard of any failures due to the tick it seems to be just an annoyance to some. My old Cobra had it FWIW, it sounds like an exhuast leak.

Supposively Ford has recently revised the head AGAIN to fix the problem but the verdict is still out.

From my research it seems as though they are concerned about inadequate coolant passages along with problems with teh valve guides....but like Jeff said it's till up in the air.

My car is an early run 03 but has not had a tick :knocks on wood:

Well the tick supposedly gets worse. I've heard sound clips from other sites where it sounds like a really bad lifter. I'm hoping there are Cobras that aren't affected.
