If you can target your averages cruise load/speed for that 3000 rpm mark, that will be about as good as it gets efficiency wise.
The BSFC curve is for a fully loaded engine at that RPM. Assuming you won't be P&G, you'll want it geared so that your typical cruising RPM is just high enough to overcome aerodynamic drag. I downshift for hills on the interstate, and I wouldn't have it any other way. And if you don't want to downshift, you could always pull a Rollie Free.
