I like the subtlety in Scott?s answer. They are the same part number. Now, will they fit? Expect to do some surgery, but hope you don?t have too.

The reason for the subtlety is that I had seen some RV-8 tips for sale in the classifieds. If they have been previously installed on any other RV, there likely will be some work to make them fit an RV-6 (the screw hole positions in particular).
