I THINK the gear pitch & tooth count is the same on the FE & Cleveland, but shaft sizes & oil pump hex remain different ( please verify this before spending your $$ ). SBF Fords 302 & 351 Windsor have identical tooth count, but different shaft & hex sizes. Check with some of the FE builders like KC, B2 etc to see where they are sourcing this stuff. I have assumed your running std pump & wet sump, If your using a dry sump then a good bronze gear will suffice as there is no pump load then.
I have always meant to look into swapping the oil pump gears for those from a 351 with 5/16" hex, enlarge the pump shaft spigot in the block & fit the 351 shaft into the FE dizzy to over come some of the issues, but the need has not arisen yet, but getting closer!!
