    Designed as part of the 128CI and 131CI Screamin’ Eagle® Milwaukee-Eight® Stage IV Performance Kit, this Second Generation of Extreme Ported Cylinder Heads has been meticulously designed to optimize air/fuel flow and velocity. Improving on the First Generation of CNC-Ported Milwaukee-Eight® Cylinder Heads, the Screamin' Eagle® team refined the intake and exhaust ports to maximize the flow of high-velocity air through the 1mm larger valves of 128CI and 131CI engines and fully machined the combustion chamber to optimize combustion efficiency.

    • Replacement cylinder heads for Air/Oil-Cooled '17-later Milwaukee-Eight® models equipped with 128 or 131CI Stage IV kits.
    • When combined with a larger bore throttle body, these CNC Cylinder Heads provide significantly improved efficiency of cylinder filling, leading to more explosive power and increased rear-wheel torque when compared to stock
    • Factory equipped with high-performance valve springs that remain stable with high-lift cams and in high-RPM operation
