What oil pan if using magnum timing cover?

Ok, so I want a 4qt pan or 5 qt? Is there clearance issues with the 5qt?
The pan in this picture hold 6 quarts if memory serves, and it sits even with the bottom of the K-member. I did have to cut out a small V-shaped notch on the seam of the K-member to clear it.
