Almost same exact peak numbers, but more average power.

Hell yes it's worth it. You will get an increase in torque everywhere since you are not only going up in displacement, but you should go up in compression as well. You may actually make better peak depending on compression.

Peak numbers aren't everything.

What makes you think that? If compression stays the same I'm betting he gets 20 more hp to the wheels with a 6.0 compared to a 5.3. Displacement is a big deal and going from a 5.3 to a 6.0 is the same gain as going from a 6.0 to a 6.7 (408).
