There are actually several criteria for selecting the best overall cylinder heads for your application. The best way to look at flow charts is to compare the entire flow curve from low lift to max lift. If you were to look at only one point, most airflow experts prefer to look at mid-lift flow. For street engines, airflow at .400-inch lift is a good place to evaluate all cylinder heads. The main reason for this is that maximum air flow at .550 or .600-inch valve lift is at the ragged edge of most streetable valve trains. More importantly, the valve is only at max lift once in the entire valve lift cycle, while the valve achieves mid and low lift numbers on both the opening and closing sides of the valve lift.
