Worse combustion chamber design ever? Saveable?

have you flowed the head? mopar 302 heads look just as bad!
I don't have a bench, not do I know anyone that has one. Maybe I'll diy a bench. Do the 302 heads have the valves sunk into the chambers almost .200"?

Edit: maybe that's why they called it the 302 head because they copied a ford 302 head :lol:
