hrmm...it's possible you just got a f22b1 block somehow? That's very odd....perhaps a "quality control thing" *laughs*. I know the blocks are identical between them, so it's deffinately possible. However, it could also be that someone messed up the block before you got the car, so they swapped in a new bottom end - I doubt that a little more though.
F22B1 = VTEC also.
