If you intend to drive this on the street, you'll miss that exhaust cross-over when the choke just won't go off. Furthermore, I'd wager that for street performance, you couldn't find any additional power by blocking that cross-over port, but you will see a drop in fuel economy and cold-start drivability. If you are building for race-only, you may gain a few HP.
