I have only ever used brass for valve guides, it works just fine.

All my engines have 360 brass valve guides. My peewee has been running for 8+ years and still runs great.

In my opinion brass is only good for ornament. The mechanical properties and wear resistance of phosphor bronzes are far superior to brass and for the sizes/amounts that are used in model engines the price difference is negligible.
