You probably need a new cat converter. From the sound of it, the engine is running fine, and even if you are running slightly rich, the cat converter should be able to handle the excess HCs.
One other possible reason for high HCs is a lot of oil burning. If this is the case, there may not be an easy solution. Valve guides would not be so bad- you just have to make sure the car was not run hot the previous day and then taken the next morning straight over to emissions testing! If you are losing oil through the piston rings, then heavier oil (synthetic will help here) will reduce oil consumption.
