Don't. You should not need to change the IMRC setup or the EEC setup either. The 95 EEC-IV works fine, and should be able to work with a 3.0 with just basic piggyback ECU tuners or a well done 3.0 specific chip (hey, we can dream!)
You will need to use the 95 lower intake manifold which allows you to retain the vacuume setup and which can then have the ports opened up SVT or larger spec.
I belive you also have to change the passenger side motor mount to the later "round" style verses the stock "square" mount. Micah here on CEG mentioned something about this from his pre-98 swap.
It can be done - as others mentioned it's in the works. I'm still planning and saving right now.
