I agree , Thanks

Check the sixth line https://hondaswap.com/reference-materials/honda-ecu-list-29129/ I also have a 1991 Civic si with pm6 Obd0 ecu as well as a 1991 integra GS with a PR4 OBD0 ecu . I have interchaned them to try them out and they are all OBD0.

Try putting some clay (plastercine) on top of your piston , put the head on ,with a couple of bolts , and then put belt back on and turn the motor over by hand a couple of times . (Mock up ) you will see where the valves squeezes the clay and can tell where you might run into problems by...

Not sure how far you want to go , but I just installed an H23 DOHC non Vtec head along with intake and exhaust, on a stock Accord LX short block .The only thing you might have problems with is the distritutor as it should be the Prelude one. (I adapted the Accord Dist with a flat mounting...
