It makes no difference. The head is mechanical, the OBD version is electrical.

The head will bolt on with minor modifications, all you need to worry about is the electronics. Any OBD1/OBD2 distributor will work, just remember that the USDM dizzy's are external coil, and the JDM dizzy's are internal coil and also have the CKP and TDC inside the dizzy casing instead of on the oil pump housing.

All this to say, its mostly wiring modifications when it comes to OBD. Either way, the ECU you should run will be an OBD1 unit, so an OBD2b-OBD1 conversion harness will be in order, and you use your original F23 engine harness on the new motor modified where ever needs be.
