A good basic rule-of-thumb is that you want the intake to flow 15% more than the heads so that the intake doesn't become the restriction in the airflow. I've found this to be a pretty good rule-of-thumb for getting the absolute maximum performance out of flow limited heads like we used to be forced to run in S/W. The performance difference between an intake that flows nearly what the heads did and one that had the 15%+ excess was significant.
