The AMS Performance Alpha GT-R CNC Race Ported Cylinder Heads are the most developed design on the market. After countless hours of testing AMS devised a port design that offers more than just peak flow numbers. And by utilizing Computer Numerical Control (CNC) machining processes, every cylinder head offers consistent and proven results. 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.
The AMS Alpha Cylinder Heads utilize the latest Ferrea Competition Plus components. Their valve train components are made from exotic alloy materials to withstand high boost and RPMs. Through rigorous testing programs, AMS identified a weakness in the factory cylinder head under high boost conditions. Their Engineering Team developed a proprietary modification that provides a better combustion seal which is applied to every set of Alpha Cylinder Heads.
These are the same cylinder heads found on the World Record holding, Alpha 12 and Alpha Omega GT-R's:
These CNC cylinder heads have been maximized to work in harmony with the optional Alpha Series Camshafts. If you would like these camshafts included, please make your selection below before placing your order.
