2 Cylinder Break

B has just started for first time after rebuild. Only thing I didn't touch is cam and lifters. Started her up today, only ran for one minute. I put 30w Amsoil break in oil in her, primed her before starting and used engine assembly lube on cam and bearings.

I have broke in rebuilt SB chevys running half throttle for 20 minutes. Tractor is still on stands and no way to load her down with a plow or implement. What's best way to seat the rings and break her in to avoid glazing the cylinder walls?
 
Hook it to a dyno and run it for an hour under about half your expected HP, do the same thing tomorrow at three quarters HP and you should be good to go.
