What head can I use on a B18A1?

[NANOO]

I got a B18A1 out of a 91 Acura Integra. I was wondering what head would I be able to swap on it to make it more efficient and what work has to be done in order to make it fit? It is going in a 91 Civic Si.

Thanks in advance

Can someone please help me on this one?? I want to swap heads but i'm not sure which one's will fit and which is best for hp gain.
Thanks again

any b-series head will fit, id go with a b16, or a b18c5 head, they will flow better than yours. it should be a straight bolt on, but you'll have to run vtec lines, cuz wasnt the b18a1 non vtec.

Yes it is a non-Vtec. How do I go about running Vtec lines and what components will I need?? What kind of hp are we talking?
Thanks

He was right, any b-series would fit. It really also depends on how much you're willing to pay. If you use a b16 or a ITR head then you'll get about 180-190hp. With a GSR head, you'll get a little less than 180hp simply because a GSR doesn't flow as well as the b16 and ITR head. You can spend the money on a ITR head, with the same flow as a B16, but with better internals such as valves, springs, retainers, and cams. Or, you can spend about $300-500 on a b16 head with the same flow but without the better internals that ITR has. Just to let you know though, I have a JDM SIR-G head for sale. Ported and Polished, has been resurfaced and was hot tanked. With intake manifold/throttle body. Let me know if you're interested or need anything else. =)
