HD Screamin' Eagle Milwaukee-Eight Extreme Ported Cylinder Heads
Description.
This Center-Cooled generation of Extreme Ported Cylinder Heads has been meticulously designed to help optimize air/fuel flow and velocity. Building on the previous Oil/Twin-Cooled generation of CNC-Ported Milwaukee-Eight® Cylinder Heads, the Screamin' Eagle team refined the intake and exhaust ports based on extensive racing efforts to help maximize the flow of high-velocity air through 2mm larger (42mm intake/34mm exhaust) valves than the Original Equipment heads and fully machined the combustion chamber to help optimize combustion efficiency.
• Due to the new race-inspired intake port geometry, these heads require the use of either Screamin' Eagle® High-Flow 68MM Intake Manifold (P/N 27300218) or Screamin' Eagle® Extreme Flow 68MM CNC Ported Intake Manifold (P/N 27300217)
• Factory equipped with high-performance valve springs that remain stable with high-lift cams and in high-RPM operation
• Screamin’ Eagle products are not available for sale and are not street legal in all countries. Please contact your local dealer for more information.
