I can't see if it's possible to stop the Component Position Report from spitting out the component value? One or two of my boards have build options, it's really annoying when the BOM doesn't appear to agree with this report and at present to prevent any confusion I'm having to manually edit every one.
The "Built In" Component Position Report File (as opposed to the "User" Component Position Report) doesn't include component value. It's also possible to edit the appropriate *.rtf file (text format) in "Report Templates" folder.
