2007 cylinder head
 

Hello I'm new to the site and new to bikes in general. I have 2007 a gz250 of course and I need cylinder head for it. Well actually I need a jug and cylinder head I have seen online where some people say that dr250 head will work and ltz250 some I've seen say and ltz125 head will work. What's the truth? Does anyone know what heads will swap over and from what year bikes? I have seen 99 - 2010 gz250 has same head but any other models ? Thank you

Chris, just a suggestion. Multiple posts on the same subject won't make things happen faster. Just a single thread will get as much attention and not cause multiple responses all over the board. I guess continuity is the word I'm looking for.
