    Blue Stripe

    so, i have read a few other forums, and have found 1,000 different answers. so i thought i would ask the guys i know better. last night as i was looking around under the hood, i happened to notice a blue stripe on the drivers side cylinder head on my cobra. does this mean anything? i think i have been told in the past that it was an updated head. is that the case?

    thanks guys.

    The only updated heads that have the 9 threaded spark plug holes were never installed on a Cobra. They were installed on the Aviator in 05.

    It has the updated head for the cooling/ticking problem. But it still doesn't have the 9 thread plug holes. Alot of the mid year 03 Cobras and Machs have the "blue stripped head", or any that have had the warrenty/recall done at the dealership.

    The main cooling issue with the drivers head is that there is no fitting in the back of the head allowing the hot coolant an escape passage out of the head, like on the pass side.
