Cam chain rollers

Getting close to putting the head back on. What do y'all think about theses rollers ? Bike supposedly has 11k miles on it. I know there is a steel one available but I'm a little reluctant, not sure about the whole steel on steel part. I guess it's okay, the 1000s use steel guide rollers. Not going to put many miles on it when finished, just something to play around on...
