Stay from AAM anything
OEM engine block is fairly stout. Proper rebuild should last a while with proper maintenance. For street car, you won't need too much in the way of engine upgrades, but you have a variety of options if you want to beef it up a bit depending on your budget.
Get the EPS oil gallery gasket and hardware kit. Oil pump gears are a known weak point but really only at sustained high RPMs, which shouldn't be a problem on the street.
