The rio is 2 and half feet longer than yours as well. The outbounds are 37.5' long and made to cast a little heavier.
So they be a touch light but that may not be a bad thing as the rod can cast off the top half pretty well. The 35' heads do an OK job on the smaller CND. For instance I use the 40+ striper line by airflo in a 9wt and they work pretty well on the rod. So your heads may be a touch light but they should work just fine.
