Have you had it running yet? Sometimes the oil flow is low enough that just turning the pump shaft with a drill motor won't flow enough volume. I'd suggest getting it running, and if there still isn't enough flow, an external bypass line can be installed. There's also a couple of sneaky tricks to unclog the internal passages, but the engine needs to be up to normal running temperature before they work well.
