My experience from years ago of fitting the oil pump gasket back to front (as you've done) on a new engine resulted in zero oil pressure. As a result, I now always fit the gasket to the block then fit the pump, rather than fit the gasket to the pump first.
Wasn't me, was the engine builder, I just bolted the head onto the block and that onto the box and transfer case but answers my question I think
