mazda b1600 na with ma head

hi guys i was wondering if anyone has done the mazda b1600 na block with the b2000 ma head and if its even worth doing the swap, as ive received a spare b1600 motor i was wondering if this was possible? cheers

the pre 86 1600/1800/2000 are completely different than the 86 up 2000/2200

oh yea i was meaning the pre 86 motors with the 1600 having an engine code of (na) and the 2000 being (ma)

oh. I have no clue on that. Try it and see I guess.
