Highest Efficiency in Their Class

AFR heads flow more than any other manufacturer when comparing heads of similar runner size and valve angles. This means a higher velocity charge with better cylinder fill and scavenging potential. The benefit of this has been independently tested and documented in many magazines, various web sites, engine shops, and various other sources as well. Simple equation more flow and higher velocity equals more torque and more horsepower. It’s the recipe for success. End of discussion!
