Any difference in obd-2a and obd-2b D16Y8 heads other than the distributer harness plug?

for example if i was to use a obd-2b head with an obd-2a distributer... any difference in the heads themselves?

thanks!

yes. one has the air injection on the intake manifold and on the head where they mate. the last time i tried to mix match them and put a air injection intake manifold on a non-air head or vice versa...i could NOT get it to seal. just a little bit too different.

yeah ive been having a blast with this air injection business, that little hole goes strait back to the hole for the injector.. why? what does this do? i understand the general concept i think but i dont get some parts.

also, if i get an aftermarket intake manifold i can eliminate air injection right?
