productive? not... funny? matter of opinion...
but the question was sort of "wide" in scope.. who makes the best car, what is the fastest color.. that kind of thing..
These things are all parts of combination's.. you can ruin a head easier than making it better and this is all reliant on what else is done to the motor..
Add this to your "making more torque" it would be likely counter productive as well.. big ports are murder on low end torque and I have bought more than one set of race ported heads off a guy to bolt on a stocker that works a lot better..
From your string of "what/who/where" things and what you are trying to do.. you might look at a turbo build.. (is a lot cheaper)
