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 Granite Highlighted
•
Factory equipped with high performance valve springs that remain stable with high lift cams and in high RPM operation
•
Ports 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 efficiencty of cylinder filling, leading to more explosive power and increased rear wheel torque when compared to stock
