The flow numbers that AFR advertises are skewed. They flow them differently most of the rest of the industry.
This article claims they picked up 104 horsepower and 53 ft lbs of torque. It would have been more if they would have used the TFS TW's.

Just to make sure. You know cleveland heads arent a direct bolt up. You have to do some work to get the water passages in the right place. But they are killer heads. My dad has a 72 mach 1 with the 351c 4bbl and those heads are kinda overkill even though they are stock.
