Designed in conjunction with the system-matched components of the Screamin’ Eagle® Milwaukee-Eight® Stage IV Performance Kit, these CNC-Ported Cylinder Heads have been meticulously machined to optimize air/fuel flow and velocity. Starting with a unique Screamin' Eagle® cylinder head casting, the Screamin’ Eagle® team has dedicated countless hours of computer simulation and flow bench testing to maximize the flow through the intake and exhaust ports.

• Black highlighted

• Factory equipped with high performance valve springs that remain stable with high lift cams and in and high RPM operation

• Ports are meticulously machined on our five axis CNC machine to increase the velocity of the intake charge and to maximize exhaust scavenging

• When combined with a larger bore throttle body, Cylinder Heads provide improved efficiency of cylinder filling, leading to more explosive power and increased rear wheel torque when compared to stock
