91 GSXR 1100, 94 GSXR 1100 carbs or Keihn CR 36's or FCR 41

I have found all of these on Ebay. The prices vary from 50-500. First off which gsxr carbs would be better and also what is the difference between Keihn CR and FCR?

The spacing on the '94 carbs is wrong I believe since it 's off a narrower watercooled motor, for pure horsepower the FCR (being racingcarbs) are the best but your powerrrrrr plant must be worthy of them.

The FCR are flatsides and the CR are round slides.

This might help too.
