used mpi System?

I'm rebuilding a 258 and am going to install a 4.0 head on it. I'm wondering if it's a waste of time to put a used mpi system onto the engine. I'm thinking that i might buy a whole old 4.0 and swap the whole top half of the motor onto my 258. I guess i'd like to know if anyone has either done this, or knows of any inherent problems in a high mileage 4.0 injection system. Do the computers/injectors/mass air sensors/throttle bodies wear out? that sort of thing. thanks again for suffering a fool
