More thinking....

You could have used a muffler bend,....same affect as filling to form the "D",
but that looks like crap !
Step the tubing ! The same size you have now at the carb..then, before
the radius go down one size all the way to the block. It will have a reversion
dam at the edge of the port.

But the thing I keep coming back too.........it's a flat head ! Lots of twists
and turns to fill the cylinder.

For my hopped upped B, I was going to make a manifold for some SU's, when I get to that point..
