Hey guys… I’m swapping the b18a head for the b18b head (larger intake ports) and was wondering if there was any difference in the cams/valvetrain. I’m assuming that if there is a difference the b18b vavle train would be the better choice but I’m not too familiar with the lift and duration on either set… any help would be awesome… thanks guys!
Pretty sure the cams are identical. But I may be thinking of the difference between the 90-91 B18A and the 92-93, so double check that.
i looked up part numbers one day and they are the same from 90-95 pr4 then 96+ they are p75.

the exhaust cam on the b18b is a little larger valvetain is the same
correct what jdmboi86 said.
and I don’t think the the B18B has larger intake ports either, unless it was ported
