AMS Alpha Stage 1 Cylinder Heads

Bread Checkout

The Alpha GT-R CNC Race Ported Cylinder Heads are the most developed design on the market. After countless hours of testing we 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.

The Most Power Across The Whole Power Band

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.

Top Shelf Components

The Alpha Cylinder Heads utilize the latest Ferrea Competition Plus components. Their valvetrain components are made from exotic alloy materials to with stand high boost and RPM's.

Engineered For A Better Combustion Seal

Through our rigorous testing program we identified a weakness in the factory cylinder head under high boost conditions. Our Engineering Team developed a proprietary modification that provides a better combustion seal which is applied to every set of Alpha Cylinder Heads
