A. SCREAMIN’ EAGLE® MILWAUKEE-EIGHT® 5 A

ENGINE EXTREME CNC PORTED 5
CYLINDER HEADS
Designed as part of the 128CI and 131CI Screamin’ A
Eagle® Milwaukee-Eight® Stage IV Performance Kit, this
second generation of Extreme Ported Cylinder Heads 5
has been meticulously designed to optimize air/fuel
flow and velocity. Improving on the first generation A
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. 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 compared to stock. The
Extreme Ported Cylinder Heads are factory equipped
with high-performance valve springs that remain stable
with high-lift cams and in high-RPM operation.
