I just got a cobra and the engine was replaced with a ford remanufactured engine assembly back in January. I am wondering how to check to see if this motor has the updated cylinder heads on it.
if it was just done in jan 09 should have the revised heads.
its my understanding all the remans sold now have them as well as they are the only head ford will sell for an oem application.
i was told all the non 05 revised heads that are being turned in as cores get destroyed due the the effed up casting so they don't get recirculated back to the public.
