Pulled the Mess that was my Timing Chain....

I personally would not use any zinc additive. The zinc levels anymore are not all that low compared to the past. And a given additive that is not compatible with the additive package already present in the oil can very well lower the oil's protectoin levels.

You used the cam lube and that has always been enough for my break-ins. The filter change may be a good idea; I never have in a lot of new engines with no issue. I personally would not drain the oil for a few hundred miles but others may do differently.

I just keep the rev's up around 1500 for 15 minutes and then go from there, making sure to varying the RPM'sa lot for a while and gradually increasing the torque used.
