Make sure you use the recommended springs with the cam. It is worth the money to get a good valve job done. HP to be gained there. If you feel confident some grinding in the throat area can reap more flow. Think of the airflow as a car and imagine what type of corner the car will be better able to take. Nice gentle smooth radius in the short side. be careful to keep it smooth. get rid of the sharp edges and blend them in.
