Rationalize it anyway you choose. But if I had to decide on whom to listen to, the manufacturer who actually builds it, or someone who's claimed to have talked to every old school rodder out there, I would choose the mfg every time. And even if the mfg is not aware of the break in procedure used, the OP still has to endure the hassle, downtime, and expense of removing & replacing the 'defective' unit. I wouldn't want that on my conscience.
