I believe that you can just plop a few new lifters in there and be done with it. No genuine break in for lifters besides priming them once in the engine, they are hardened, very hardened. But... I do this when installing lifters and it's never failed me. When priming the lifters after installation, have someone turn the primer drill (if using one) and turn the motor by wrench nice and slow until you have completed 2 rotations, with the drill/primer going constantly, then adjust your rockers accordingly.
