[Closed] Replace full headset? Not sure what I need

Some rough headset action coming from my road bike. The bike is a Wilier Izoard 2008 carbon frame, with carbon forks.

Headset's a Ritchey, but not sure which one, possibly Ritchey Pro. Don't know whether it's DropIn or Integrated or what. Can anyone help?

Bearings say 41.8 x 30.5. 45deg x 45deg.

Here's some photos.
