RE: Engines
There is no difference in performance aspect. The Romeo block was built in the "Romeo plant" was used for car based engines. While the Windsor block was made in the "windsor plant" and was primarilly used in trucks. But the 99 and new mustangs had a mix of both.... The major difference between the two is the main bearing caps and the main bearings themselves. Each engine uses different main bearing sets and arent interchangable. If you have a windsor block it has a "W" cast in the front of the block. Other than that, thats all that is different between the two. I got this information from Sean Hylands "4.6 liter ford engines" book. There may be more, but this all he mentions.

RE: Engines
Also the late Windsor blocks were known for having a very nasty 'piston slap' upon start up.
Even some of the early Romeo 4.6 blocks had issues with piston slap. I lost the short-block on my 02 GT with about 28,000 miles to piston slap. Everytime I started it, it sounded like someone was taking a hammer to the side of my engine for about 30 seconds.

RE: Engines
I also found out that the heads are also either windsor or romeo. The way to tell if your block is either, count the bolts on one fo the valve covers, if you have 11 bolts then you have a Romeo block, and the cam gear is removable on the cams. If you have 13 bolts on a valve cover then you have a windsor motor. Cams on a windsor motor have the cam gear pressed on so you will need to order new cam gears in addition to the cams.... I am ordering new cams this is how I found this out... I have a Romeo, yay! Also windsors are stamped with a "w" in the valley under the intake manifold. I was told you can just look down with a flashlight and see if you have one of not.
