Don't use that stock intermediate shaft or a used gear of any type. As mentioned above, Hughes Engines sells the bronze gear and the melonized gear. With a new cam, I would use the melonized gear for longevity.

Make sure you use a distributor collar to limit the up and down movement of the gear. Left uncontrolled, the gear can move up and down too much, which really accelerates wear, especially on the bronze gear. Also check your intermediate shaft bushing for excessive play.

I have wondered if cryogenicly treating the bronze gear would be of any benefit, but have never tested that idea.
