Yeah, it depends on what material the cam is ground on, more specifically what material the drive gear on the came is made from. (popular option is to have a standard iron gear pressed onto a steel cam core) Best to call the cam manuf if you have the cam card.
If it's a GM steel roller cam you can likely use the GM Melonized gear w/o worry.
If you don't know what the material is, you can pull the cam and look at the numbers (big job)
You could use a bronze gear (ugh).
If you have a stock oil pump you could use a Comp Polymer gear (what I use) High volume pumps tend to chew them up.
