Swapping ecu's will probably be the most cheapest and possibly the most effective way to get more power gains on a stock Silvertop. Although changing a few wiring pinouts and installing a map sensor is another thing to add, it would make for a great setup to really utilize the ITBs on the 20v. If you want to install cam gears, keep in mind that it won't make much of a difference on a stock engine unless you install more aggressive cams and sacrificing vvt (Use of cam gears removes vvt capability since intake vvt pulley needs to be removed). So, if you do install cam gears, don't get a blacktop ecu, get megasquirts and fine tune it. The downside to it is that megasquirts can be expensive.
