Roman has instructed me not to pull all the way to redline yet due to the crank pulley, since the belt won't be properly tensioned. I'm going to check the tension by hand to see if I can be relatively sure it is safe for a WOT pull, now that the S/C has at least an hour of idling (most done by Alekshop to stabilize the idle) and 80 miles of driving worth of break-in time, and will report more.
