b16a honda head

i have a b16a engine what heads will work on this engine?

b16a, b16b (Civic Type R), b18c1 (Integra GS-R), or the b18c5 (Integra Type R). The intake manifold bolt patterns is different for the B18C1, so that's probably not the best one to go with unless you're going to get a new manifold as well.
