Exhaust Port Shape and Header Flange Shape

I have "D" port heads for my 327, and need to know the most efficient way to shape my headers where they mate to the ports. I realize that the header MUST be larger than the head ports, but where should I put the "step" in the header...........on the floor, the ceiling, or both? The "D" port flanges that I bought are exactly the same shape as the head ports, but are 1/4" taller than the head ports. I need to know how to orient the flange in the vertical direction, which will determine where the step into the larger header will be.
