It can, depending upon the particulars of the specific engine. It's easier
to empty a cylinder than fill it so you need more intake flow relative to
the exhaust. If the heads are such that the exhausts flow better, than
reversing them can improve power. Also, it may be easier to optimize the
intake and exhaust for a particular package. For instance it may be easier
to construct intake stacks where the exhaust was and do a bundle of snakes
in the interior of the vee. The Ford Indy DOHC V8 was that way.
