*Product Release* AMS Nissan R35 GT-R Alpha Series CNC Ported Cylinder Heads

AMS Alpha CNC Ported Cylinder Heads

The Alpha GT-R CNC 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.

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.
