Not defending the work, but manufacturing a flat surface is actually pretty difficult without machining it. The larger the surface the harder it is.

Which is why all of these cheap headers don't have them.

A bench top belt sander will get it good enough, but instead each port looks like it was done individually, because of the differences in flatness and height. Yeah, I don't believe it's too hard to get a header flange close enough.
