if they are the same how come the 90-93 intake manifold for the integra doesn't fit, you have to pdo some porting or somthing..... that's what i read from someone from honda-tech.
so which is it? OR the B20 head only identical whe compared to the 94+ LS heads?

Ummm, No. I have a B20 and am currently using a 2G Teg Intake manifold. The B20 and the Ls both have 81mm combustion chambers. I believe StorminMatt from the CRX resource has done testing and found the heads to not be the same part number. But all measurements are identical, that he knows of.

by 81 he meant, 81 mm diameter combustion chambers
I believe the combustion chambers are 45cc in volume.

Coolant jackets in the head, larger? hrmm....more wackiness... I would think this would be possible with the B20 block, as the siamesed cylinders would allow more room, but in the head? Wierd stuff....

i think that there are different cams in b20b than b20z, one of them has the same as LS, the other has longer duration ones.
