Hi,
I currently have a Chorus 50/34 Compact. The crank is a chorus CT Ultra Torque crank. I was wondering what kind of chainrings I would need to make it a standard 53/39 crankset? Are there any compatibility issues with these chainrings?
Thanks for any help!

It's probably easier to just swap out the crank and sell your compact. There's lots of demand for compacts so it should move fairly easily. I checked a couple of on line sites and didn't see 53 or 39 toth rings for Campy compact. Check your derailleur too. If it's a special compact one, it might not work very well with the regular rings.

I think TA-specialties, Stronglight or Miche will have chainrings, which ones fit may vary with the year of manufacture of your cranks.
Some options, depending on your cranks. I have only used TA-Specialties on Shimano cranks but that worked fine. As C50jim said it may be a better choice to sell your compacts and buy a 53/39 if you aresure that is what you want.

Dont think it's possible to put 11 speed Campy rings in that configuration onto a compact.

I read somewhere that Campy will be offering semi compact 52/36 rings with a 110 BCD at some point. Miche already do so they might also fit, as mentioned above. They might flex a bit though.

Just buy some TA Specialites Nerius 11 chainrings:

They have both a 39T inner and 53T outer in the compact 110mm bolt pattern. But you're probably going to also need these if you have a 2011/2012 Chorus crankset that has a threaded inner ring rather than separate chainring nuts:

Lots of good information about using aftermarket chainrings with the 2011/2012 threaded inner chainring in this thread (jump straight to page 3 for the conclusion):
