Right, but that does not necessarily make it so from the factory.

I'm still waiting for someone that has measured a factory original that is proud. Between the ones I've measured, and people that I trust that have measured them, I have not heard of any being positive. There could be some due to factory tolerance differences, but I have not seen or heard of any. They ranged from very near zero to 0.008" below.

I have run 915 head on a 1.932" CH 68 383.
