Big block oil pan options

I have a 187 oil pan I was planning on using on my big block Dart. However, I think I would like to have a little more oil capacity. I know adding some depth to my 187 pan is an option but what I would like to know is, are there any aftermarket pans available that don't interfere with the steering linkage on big block A-bodies? I haven't seen any yet that are notched like the 187 pan so I wonder if any of them will work without being modified. Also, I will be using a spool type DC k-frame and TTI headers should they be a factor in choosing a pan.
