AMS Evo CNC Ported Race Heads

The AMS EVO VII/VIII/IX CNC Cylinder Head is the best performing and most developed design on the market. After countless hours of testing we came up with a port design that offers more than just peak flow numbers.

Flow bench numbers don't always tell the whole story. Most vendors just state their peak flow at max lift. Their head may flow 270 CFM at .500 lift but what about flow at lower lifts? The flow at low, mid and high lift has to be balanced a certain way to achieve the most effective power curve. We have developed a CNC program that not only brings consistent performance and quality but also makes the most power of any head that we've ever tested including our old design!
