Both the aluminum and cast iron heads come with Harley-Davidson's Screaming Eagle twin cam design, which features four valves per cylinder and a high-lift, high-duration camshaft profile. This design delivers superior combustion efficiency and enhanced power output. Additionally, the heads include high-performance intake and exhaust ports, which ensure optimal flow of air and exhaust gases.
Installing the Harley-Davidson Screaming Eagle Twin Cam Heads requires the use of Harley-Davidson's Screaming Eagle cylinder head gaskets and the appropriate head bolts. These components are sold separately and are designed specifically for use with these heads to ensure a proper seal and optimal engine performance.
In summary, the Harley-Davidson Screaming Eagle Twin Cam Heads (Part Numbers: 16927 for aluminum heads and 16928 for cast iron heads) are a premium upgrade for your Harley-Davidson V-Twin engine.
