I had someone tell me the only Maxarias Heads are none placeable but I've seen 2. Also my Aikar Head has blue text but not it item frames, I just seen one with white text in an item frame and I got them to place it for me and it was indeed Aikar. So are these heads fake or real? .
Only max head I am aware of that exists is this one http://empireminecraft.com/wiki/maxarian-head/ Read up on it. Regarding the Aikar head, I would have to see it. There are a couple different versions that I am aware of, from the ppp to the pvp head, etc. Maybe talk to a 'museum' owner or someone familiar (or post screenshots of them).
The Maxarias head is probably fake, as the only true placeable one is in krysyyjane9191's head museum. Actually, I guarantee these are either all faked or renamed with an anvil, or their names would not show up when you hovered your mouse over them. However, they could definitely be legitimate heads (like a krysyyjane9191 head, DP Aikar Head, etc.) just renamed. EDIT: Just saw your screenshot, and the Aikar head on the right is definitely renamed with an anvil, so it may be just the head of someone with an Aikar skin. Or a renamed DP head, of course.
The drop party one may be legit, renaming cannot put lore on it, correct? Still get the opinion of someone like Faithcaster, mman2832, FDNY21. <--hope you don't mind guys... They will get you the info you seek.
