    b18a1 is obd0 and 1 and b18b1 is obd1 and 2. There are minor differences, everything is interchangeable.

    IIRC the 2000+ b18b1 heads flow the best and have minor changes to the cams.

    Yes, you can swap one with the other. Just make sure to use the accessories (distributor, intake manifold, etc.) that goes with whatever OBD setup your car is running.

    And for the differences, see what 92civicb18b1 said above...
