408 stroker oil pump

OK. I removed the washer from the main bolt and when the oil pump is flush with the main cap where it is bolted, the part that goes down into the cap where the oil pump drive is does not come in flush contact. It is hard to explain so I hope the picture helps. It doesn't need to be ground as the pump no longer hits the bolt. Do I have a bad pump??

Thanks.
