Porting throttle body and heads

The TB will allow more air to flow in due to the bigger diameter but it usually won't make a huge difference. It will work better with an intake, header, and exhaust system. As for porting the heads, this sort is the same too. Basically grinding out any uneven spots, sharp edges, etc, to allow the air to flow more easily.

you will lose low end torque doing it to an otherwise stock engine
