I THINK (?????) that the heads are identical etc and you just need to drill/mount a crank sensor somewhere near the gearbox,of course you need the flywheel from an efi so the sensor can read the holes in the fly to run the car.
Fuel pump wise I'm not sure you need to worry to much about the existing set up as the mfi boosts fuel pressure via an accumulator so theoretically you should be ok just using the original mfi pump to power the efi system as efi runs on lower pressures than mfi.
