the dent mark that would go to the front of your engine if std direction rod tag to out side of the oilpan rail.to get the dent to the back of the engine you would flip bank 1.3.5.7.there new home would be 2.4.6.8 now your pistons then will have the right off set .your crank oiling will be fine .but your rear main seal needs to be for a rev direction or the oil will rope right out of the seal. i would fix this your rods are running around the crank the other way around the off set helps on the side loading
