Definately worth the price of admission. Heads are the key to making power. If you port them, it'll make more power assuming you're reving the engine high enough to flow the air. Make sure you take them to someone who knows what they're doing. If you don't know what you're doing you could actually hurt the velocity of the airflow. Now all you need is some forced induction to take advantage of your newly ported heads!!
