I have some RAF files that show nasty distortion that isn't present in the JPEG 
files.

Pretty sure.
There's a wealth of shadow detail in the RAF files that isn't in the 
jpegs.   So much so I've pretty much given up shooting jpegs.

However on one of my older one when I was experimenting I have

RAF
===
Raw Image Full Size             : 3328x2464
Raw Image Width                 : 3328
Raw Image Height                : 2464
Exif Image Width                : 2048
Exif Image Height               : 1536


JPG
===
Exif Image Width                : 3264
Exif Image Height               : 2448


So yes, if you look just at the EXIF size..
But what are you looking at in the RAW with the exif size?  Isn't that 
the "embedded jpeg preview"?  The "Preview Image" entry.

Mention at http://en.wikipedia.org/wiki/Raw_image_format

* Optionally a reduced-size image in JPEG format, which can be used for 
a quick preview

The "reduced size" is the part which explains what you are observing.





What you are working with is the raw data.
