Power Difference between 2007 YZ450F and WR450F

Just wondering what the power difference between the 2007 models YZ450F and WR450F. Does the WR have much of a noticible deficit, or is it just in the way the power is delivered?
Also, if there is a big difference, can the WR be modifed to make it on par with the YZ?

The WR is sneaky fast! Even the SX guys use a WR cam in the YZ.
If you really want more power you will need to go to bigger valves with higher lift cams.

they change WR to an YZ cam?
