Somewhere in the Turbo Dain thread is a pic Of My Oil Pan and you can see the impressions of 4 parts of the Oil Pickup on it.
With the Pan removed I beat out the dents.
What you need to worry about is if the Oil Pickup is cracked and the Pan is holding it together. There is 4 raised squares that keep the pan from easily blocking off the Pickup Screen
