Wouldn't it be nice to have something like this
http://www.aempower.com/product_cam.asp for such instances. Has anyone
ever made an adjustable cam gear?

Actually quite noticable change in location of power band can be
obtained by advance or retard of cam. Advance cam for more low end
torque; retard cam for more torque at high RPM. Closing of intake valve
is the influencing factor. One tooth on cam sprocket is too much & may
cause piston-valve contact. After locking sprocket onto cam taper, turn
engine by hand to insure no interference between valve & piston. I do
all highway driving so 1/2 tooth retard gives better power at high
speed. Be real careful, double check for interference before starting
  Not that there may not be some merrit in miniscule advance
