Carreras are known for failures of valve guides. However the oil is a symptom not a cause of the failure. The failure is the guides wearing out and some of us believe that is caused by lack of oil getting past the seals. I think the white seals you are using are the best choice for allowing enough oil to pass to keep the guides lubricated. This doesn't mean you don't need to lube the valve stems/guides before the first start.
