It's called "Siamesing" the runners.
The end result is this:

not Jeal's, but the same thing. Siamesed Plenum

what the different than Jeal's work?
i wanted to know how those area looks like before sanding and
polishing, is that Original surface is bad,that we must polish it?

Hadi, on Jeals siamesed plenum a 36mm ball would not go thru the siemesed ports or slide it back and forth in the siamesed port.

Don't mean to start a war, but couldn't an oval (or oblong) shape have a higher volume than two circle shape ports (even with a slightly bigger radius)?

Yes they could have a higher volume, bottom line though: bigger is not always better. The key is to tailor the intake to the motor, a mild 350cid will have different airflow needs than a full tilt stroker.
