There is your answer... the 4500 top would just simplify the EFI conversion and not require the adapter between the throttle bodies and the top. If you want the six pack then that is what it is. Now, that said, I think it would be possible to make a top that is an adapter and bolt the EFI throttle bodies to it instead of the top that comes with it. That can also give you the opportunity to adjust the plenum volume. Building the top would eliminate the extra height of the adapter.
