SCREAMIN' EAGLE SCREAMIN EAGLE MILWAUKEE-EIGHT EXTREME CNC PORTED CYLINDER HEADS

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.
