Heads question

To add to what Perfacar and BJ said. Adding the flow numbers @ the different lift values and averaging them will give you a better look at total flow from seat to full open and back to seat. Big numbers up top in the lift cycle doesn't usually make the best power. The head with the most average flow will just about always make better numbers on the street and the strip, ..usually. Unless your building an 'rpm' motor like a pro-stock, that thrives on rpm and will not see anything less than 5000. The most flow with the smallest port at the lower lifts...equals BIG torque and power, equals great street manners. And lots of tire smoke. I said all that to say...I agree Perfacar and BJ. Terry.
