I'm a little concerned about the headers I got for my B.
A. When you hold a straight edge against the flange, the clamping surfaces are
not level. Some are off as much as 1/16"
B. As you can see from pic 2. The 'ridge' is as narrow as 1/16" in some areas.
down to 1/32" on one port. I have a feeling that is going to be a perfect
place for blow by.

A neighbor said to leave that ridge alone, but i'm thinking of milling it down
flat with the rest of the flange.
I can either use a belt sander and take down 2 ports at a time, or go the time
consuming route and fly cut it with my milling machine.
