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.
