I wanted to mod Omega Supreme's head to look like the cartoon (clear shielding, gray inner helmet, orange face, blue lightpiping) but that thing is glued tight. Taking out the 2 screws does nothing...unless I'm missing something. The neck has regular pins. The base of the neck has a huge flathead pin. I'm hesitant to pry the head pieces apart. On mine, there is a slight gap on top where I could wedge in a razor or even LEGO separator to get started. But again, I'm hesistant and from prior experiences, this process will usually break the internal tiny pegs (if there are any). Jetfire's head was easy to take apart because there's no glue. Because of how lightpiping works, color choices are limited if the plastic is not clear. Shining a bright blue LED will just make the eyes look...yellow. Shining a bright red LED, however, will make the eyes look orange. The cannon ponytail (for lack of better term) is completely optional. It's not used in alt mode. So, if you like it for nostalgia reasons, then great. If not, the cannon ponytail can collapse down to give a cleaner head look.
