I would still use a small break-in period.

Yes, the lifters have been burnished to that camshaft, but the lifter bore positions vary from block to block, and even the lifter bore clearances vary.

A lot of guys buy cams already broken in from Cam Research, since they have a "cam break-in machine" and I have heard of several instances of the cams failing even after that procedure.

Not trying to be a negative Nancy, but just urging you to be cautious.
