Just make sure your camshaft end play is correct. Too much movement front to back will destroy the gear real fast. I've seen the bronze gears fail in a hundred miles or less.

I've never had great luck with the bronze gears but they have their purpose. I don't think you can wait a year to check them though. I use the melonized GM gears on all of mine, including billet rollers; however, the billet rollers I used had a cast distributor gear pressed on as requested by me. DO NOT use a steel gear on a billet core without the cast gear on the cam.

In your case I think you should have good luck with either polymer or bronze, but make sure the cam end play is spot on and I'd inspect it often, at least initially.
