I found when i went to replace parts in the head that the v1 to v2 had small differences. You can get them to work but it just takes a little thinking and know how. If there are parts that are direct fit then i def. did not find those. JEEP said he wanted something to bolt right in so that he didnt have to mess with the head. I just steered him to the two stores. If you look on their websites, most of the parts for the head are different part numbers if im not mistaken. Just trying to keep it simple as possible for him cuz I know this stuff can get really confusing.
