What gear to run with cam

I also contacted CompCams recently and here is what they said
"The part # you gave me, 20-000-9, will use a bronze gear or a composite distributor gear." I followed up with a call and the person said a cam ending in dash 9 (-9) requires a bronze or composite gear. They can grind a cam on a dash 8 (-8) core and that would be fine with a stock type gear.
