Need some help here. I'm working on a 2014 400, the head is trashed. I'm looking to simply buy a complete head up set up to fix it. Using the same cylinder. Anyone know if any year head up will work? I've compared part numbers and they are indeed different, but they did change the name from 400ex to 400x and thats making me think that is the only reason for the change.....:ermm: anyone able to tell me for sure???????? Thanks

as far as i have ever known, they are the same.

not sure on why it would have a different part number though,
