another thing, the ls intake manifold is the same on all ls's right, so the 90 ls intake mani I have sitting around will work just fine, correct?

*edit* but using gray plug sensors, throttle body, etc. correct?

i'm guessing yes also, if not, i'll just have to cut a hole in my hood to clear the giraffe intake.

90-93 integra LS intake manifold will work on your b20

thanks, i was kidding about the hood. I do need to know something else though. Are the b20 heads and b18b heads the same. I know the blocks have different bore sizes so hence I was wondering if the combustion chamber is larger on the b20 heads? I know they use all the same parts for internals, but, ugh, if they're the same, i'm going to pick up this complete ls head and have it worked on while i'm out of town.

my bet is that the B20 head has th esame valvetrain pretty much as the LS head but of course th B20 head will have chambers that are bigger to fit the B20 bore.

Yeah, I mean that was my guess. Although, it could be wrong, would the 3+mm bore size make that much of a difference, couldn't a machine shop increase the size just slightly so that it would be the same, or modify it to be perfect for my application, if so, wouldn't the ls head be better since it has more material to take off the combustion chamber to modify.

The B20 uses a P75 Head Casting just like te B18B, and it doesnt have a 84mm Combustion Chamber...only an 81mm...
