I think there was an early production issue with the 03 heads (both Mach and Cobra) and this issue was fixed in later part of 03 and did not affect 04's. I am not sure if it was the guides, but it dealt with head tick. Also I have read something about 04 heads have a improved cooling, but I have no idea how.
