The LIM'* should be exactly the same, but if the LIM is still on the donor motor, and it does not have aluminum framed gaskets, then remove it and go with aluminum gaskets before you proceed.
Make sure to look for that thread I mentioned, there are pics of what the guy did to get it to work.
He had to drill a hole in the throttle body in a certain area, and tapped it, then put in a 3/8th" barb, and ran his EVAP from there, or something like that, I'd have to read the thread again, as I have done the swap myself.
