I've also had it take minutes for lifters to pump up, after changing pushrods. When you rotate the engine by hand or release pressure on a lifter by removing the rocker then put it back, there's no oil pressure, so the oil can drain out of the lifter, not the same as just shutting off the engine. At least that's my guess.

They are known to sell the "enginetech" brand stock replacement. These are known to have issues and some of the arms have failed. I know of one hear locally in town. When I asked him where the rockers came from, He named the same place... They also failed in the same fashion.
