Unlike when you try to use the original head from Ginrai/PMOP in Jinrai Prime (and the mess of joints and hinges completely gets in the way of having any neck rotation) you're perfectly able to get full 360 degrees of head rotation, and since the headmaster's neck is a ball joint you can even get a little bit of a tilt, and up/down articulation going on as well.
On top of that, unlike when you'd try to use the original heads on this mold, you can store the super mode head in the chest while the headmaster is inside it. You just need to turn it slightly and it fits perfectly fine.
