I would not use bronze.

Response to Steel gear

It will wear.

If you have a cast core camshaft, then use a cast iron gear. If you have a billet core camshaft, then use a steel gear.

That rule has not let me down in 15 years.

A lot of camshaft companies will tell you to run bronze gears because they simply don't sell steel gears, or you get a GM fan on the tech line.

Another major factor in how well a gear survives is the installation dimension. Ford gears are not like GM gears. You can't just pop the old one off and put the new one back in the same place and put the pin in. The install dimension needs to be checked and rechecked upon installation. There is a spec and the gear has to be in that spec, or it will wear or cause major damage.
