Top fork-clamp doesn't matter. It's distance from head-tube of frame to ground along pivot axis that determines angle. As long as lower-bearing didn't raise frame; it'll be same as before.
Even if it did, tiny amount of change involved wouldn't make that much difference in handling response on street bike. If you want snappier turn-in, lower front-end by 20-30mm. It really requires that much change to be noticeable. That's because rake-angle changes pivot frame around rear-axle, so you'd have to raise & lower head-tube of frame significantly for just 1-degree change.
