Not true at all, several B series motors make more power, particularly the B18CX's, and the H22 has a completely different head than the F22B does, not just that it has VTEC.
chrono404 wrote:Yes. It needs to be a F22b though. the F22a is a no go. the H23 head is dohc non-vtec so really see the point. the f22b is either sohc vtec, or dohc non-vtec. The H22 dohc vtec head will bolt on just fine as well.

Look at the pics.., the only difference between the H motor and the F pictured above is the head characteristics. Yes, the H head has much more internally in order the be vtec capable, but what it comes down to is that both heads are dohc, one is vtec, one isnt. the block casting is exactly the same on the two motors as well.
as far as the more power then a B comment, i partial - failed. lol. the b series comes with more juice in some instances, but that is with the upgrade ITR valvetrain from factory as well as the bump in compression. i think if you treated this motor to the same treatment from factory you would undoubtedly incur AT LEAST measurable similarities, but i would expect that an f motor with a built valvetrain and higher compression numbers would easily surpass the 210 crank hp mark that the b series boasts. i would go as far to say a simple tune would allow for 200-210 hp.
my .02 anyways.

pix arent everything. the h block and f block are not the exact same block. materials of which they are made of come into play big. not to mention dimensions. either way they are very similar and yet very different from each other
