magnum belt accesory and LA belt accesory

i have a magnum water pump on a magnum front cover and magnum block with la heads and intake etc, and am running all magnum front belt drive accesories lie alt. pwr steering the crank pulley belt tensioner and idler pulley. my question is i that will the magnum water pump im running work the same way? i know that it spins backwards but it still pushes it into thee block and as far as i can understand it does the same thing as a la pump. i dont see any reason why it wouldnt work they both move coolant the same direction

i found this article and this guy is asking the same question mine is just reverse of his (a la water pump onto a magnum)
