When I was going w/forced induction I was not too concerned about peak airflow numbers,more influenced by what size the intake port window was. I guess I was thinking outside the box also.
Do you have any pics of that cylinder head? It would be intersting to see if your friend raised or widened the intake port or left it as stock size.
As far as lump port or not to lump port I still think it's a good idea for certain appliacations but not all.
