These are the results that Muscle Mustang and Fast Fords measured in their comparison test last year on street performance heads. The HP and torque values were all measured on a dyno on the same engine slightly modified from stock with 306 ci and a Comp Cams XE264HR cam with.512" lift on a 114 degree lobe separation. duration was 212/218 at .050 lift. They noted that the best flowing heads didn't necessarily make the best HP and torque either. Check out the flows on top and the HP & torque below and you'll see what they found out. Good information to help you decide which heads are for you!
This came from the September 2003 issue of MM&FF magazine if you want to read the whole article and can find this copy of the mag. Enjoy!
