The most advanced Twin Cam performance cylinder head design available. Screamin Eagle CNC Ported Maximum Velocity Area (MVA) cylinder heads create power across the entire RPM range by maximizing velocity through the intake ports. Increased air speed velocity through the ports is achieved by "right sizing" port volume at 98cc, lowering the port roof, and by precision-machining the shape of the port to complement the giant 2.120" intake valves. Screamin Eagle CNC-Ported MVA Cylinder Heads conquer a unique engineer- ing challenge, and provide the highest possible torque and acceleration at any RPM. MVA Heads will boost the punch of a 103" engine. When paired with high lift cams, MVA Heads can give a 110" or 113" motor everything it needs to achieve new levels of performance. Countless hours of dyno test- ing resulted in a 95cc combustion chamber that performs in perfect balance with the port size and shape, and reduced detonation. MVA Heads feature Screamin Eagle Race Springs that permit the use of high lift cams (up to .660"), and are machined to accept automatic compression releases (sold separately) for easier starting. MVA Heads are manufac- tured and assembled at Harley-Davidsons world class engine factory in Milwaukee, ensuring every set is made to exact tolerances.
