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



Fit Replacement cylinder heads for '17-'23 Twin-Cooled Touring models equipped with Screamin’ Eagle Milwaukee-Eight 114 or 117ci Stage IV Kits. All models require ECM calibration with Screamin’ Eagle® Pro Street Tuner for proper installation
