I did it to my 91. You need a dizzy, the head.and intake. Use the newer throttle body, and you have to do some pinning to plug the dizzy in. its not a bad job, i figured it out myself in high school with some wiring diagrams.
The big advantage you get from this conversion, which does not require a computer change, is the ease of timing advance change. Without a tuner it is unchangable with the 8 plug. The 4 plug intake and head are better for performance (i think) than the 8.
All of the 2.3 heads from our engine family will fit your engine block, including the 2.5L Ranger. Other than the Esslinger SVO head RACE ENGINEERING - Cylinder Head - 2300 - 2500 - 2700 - 2850 - Race Engineering, Inc and the Race engineering head, the castings I like the most are the last single plug castings, available on Mustangs, 87'-90. Ironically, they don't flow that much in stock form, but a few hours with a rotary file, can make a huge difference with them.
Here's what the un-ported airflow looks like on the 87'-90 casting I recently tested.
You can use a head from a ranger up to 2001. After that the changed engines. There is not a diagram that can be used specifically for this conversion. I do however have the diagrams, and pin locations to do it, i have already went through this somewhere in these forums, if you look around its there. Also, any head from 88-on ranger and 91-on mustang will not be compatible with a distributor. they are all 8 plug and the intakes et in the way of the distributor.

Hey guys im looking to build a 2.3 for a race car, most motors ive found are fuel injected 2.3s, can i take the 8 plug head off, switch it with 4 plug from an older model and run carburetor and do away with all computer and stuff,
Been researching engine swaps for my 1957 Austin Healey 100-6. Thinking about a 2.3 turbo with a T-5 transmission.
Lots to digest. Use an 87-88 Thunderbird 2.3 Turbo, Mustang SVO, Ranger roller rockers, Duratec etc??. Can anyone point me in a direction? What is the best combination of engine...
Well this is a shot in the dark since this section is pretty dead, but hopefully there's one or two lurkers out there that could help.

I have a Ranger 2.5 intake. Motor is stock. Aside from UDP headers and exhaust and 17lb Bosch injectors. Has an SVO 5spd swap and 3.73 gears. I'd like to have it ported before installing it and half shaft the TB. In the future i would like to step up to a 2.5 ported head as well. Question is do...
