but if it's an d16z6 Si head, it will work. I'm not sure how the wiring will go. I don't know if you'd have to convert to obd1 for it to work.

if its a z6 head, dont bother, it will lower your compression and hurt the power. and if its a b16 head, then no, it wont work. but the head is worth some money. or you could get a b20 crv motor and put the head on that (not a direct swap but pretty easy, its been done a lot.) that would make a vicious dohc vtec motor, though the reliability is questionable.
