B20 Head On A B18a Block

[BodyDroppedNikes]

i was thinking about putting a B20 head on my B18a (i have a 90 Integra GS) and was wondering if it can be done?? i know it sounds like a dumb question, but i dunno shit about B-series motors. IF it can be done, what all will i need to do it and what will it cost me for parts? also, what power gains (if any) can i expect? thanks

no point ... as far as i know they are the exact same heads

The intake manifolds are different. The B20 one won't fit under the LS hood. I believe the header on the B20 is different than the LS, but can't confirm that. They are essentially the same head.

Well you would gain the difference between the B18A and B18B if it's got B20Z cams. You'll need a head gasket and some new head bolts at a min. It's a good Idea to do the Timing belt and H2O pump while you are at it.
