Introducing the Harley-Davidson 1650013A Screamin' Eagle CNC Cylinder Heads for the Harley-Davidson Twin Cam 103 and 110 engines. These high-performance cylinder heads are precision engineered to deliver increased power and torque, making them an excellent choice for riders seeking to enhance the performance of their Harley-Davidson motorcycle.

The Screamin' Eagle CNC Cylinder Heads feature a unique design, with each head being CNC machined from a solid block of aluminum. This process ensures a perfect fit and finish, as well as optimal engine cooling. Each head comes with large, 41mm intake ports, which provide increased airflow for improved combustion efficiency.

The exhaust ports have been carefully designed to optimize exhaust gas flow, reducing backpressure and increasing exhaust velocity. The heads are also equipped with large, 4-valve combustion chambers, which provide better fuel atomization and more efficient combustion.

The intake and exhaust valves are made from high-quality, titanium material, which offers superior strength and durability compared to traditional steel valves. The valves are also larger in size, allowing for increased air and exhaust flow.

The Harley-Davidson 1650013A Screamin' Eagle CNC Cylinder Heads also come with high-performance, roller rocker arms, which provide smoother valve actuation and reduce friction. The rocker arms are adjustable, allowing for fine-tuning of the valve clearances to ensure optimal engine performance.

In addition to their performance benefits, these cylinder heads also offer a distinctive appearance, with their polished finish and Harley-Davidson logos adding a touch of style to your engine.

Installing the Harley-Davidson 1650013A Screamin' Eagle CNC Cylinder Heads requires some mechanical expertise and specialized tools, so it is recommended that the installation be performed by a qualified Harley-Davidson dealer or mechanic. However, the included installation hardware and instructions make the process as straightforward as possible.

In conclusion, the Harley-Davidson 1650013A Screamin' Eagle CNC Cylinder Heads are a top-of-the-line performance upgrade for Harley-Davidson Twin Cam 103 and 110 engines. With their precise CNC machining, large intake and exhaust ports, high-quality valves, and roller rocker arms, these heads offer increased power, torque, and efficiency, making them a must-have for serious Harley-Davidson riders.
