Greg, I was just giving you a little hell about relying on these tech guys. I've had very little success with that. They usually have a very limited window of knowledge and have a special interest in mind.
I think you are making the safe decision for the camshaft using a bronze or plastic gear. I've seen bad feedback on both so it's a toss up. As long as you check it often like a valve lash as Greg mentioned. The main thing is you took my advice and plugged the bypass. IMO the brass AND plastic gear are likely going to wear quickly and the debris would have gone through the bearings and caused an engine failure in the near future. It's just a compromise all the way around.
I absolutely wouldn't remove the orings from the distributor. Your bearings and valvetrain are much more important that your gear. I've seen people file a slot in the bottom pop out for a little extra spray.
