Both brake faces are guaranteed to run out less than 0.001" reference to the mounting flange.
It is vital that the mounting face on the hub is perfect. If not, the face should be skimmed true by a precision shop. The assembled hub should be skimmed for the minimum metal removal whilst looking for 100% face clean up.
When bolting up, take great care to pull down evenly and in sequence to avoid introducing any residual distortion.
N.B. If newly converting to a double disc set up the mounting face on the previously unused side of the hub is unlikely to have been skimmed true.
