stupied question on head removal

[suprabahamut]

okay I have worked all today on the supra the head is lose and can move but it will not come all the way out, what could it be stuck on. there are some sensor wires that look like they go under the intake manifold, but it does not say much in the haynes manual about removing wires. what are all the wires you have to unhook to get the head off, and what to do with the fuel rail hook ups they seem to be in the way also, {I have unhooked them but they are a weird shape to get out from under the intake maifold}
