b18a1 with b16a head or b18c5

i gotta 93 acura integra. i don know what will be better ( faster ), a b18a1 block with a b16a or a b18c head or a whole nother b18c5 motor. should i put a b16a or a b18c head on my b18a1 motor or should i just buy a a whole b18c5 motor?

it depends one the on $$$ you have ..If I were u then i would go for the B18a1 with a b16a... the b18c5 is much more $$$$..and the b18a1 with b16a head is less $$$ so it's all on you.
