Edelbrock Performer RPM Cylinder Heads plus Victor EFI Intake Manifold for GEN III Hemi

  Edelbrock now has Gen III Hemi Performer RPM Cylinder Heads that fits 2003-present 5.7L, 6.1L, 6.2L, 6.4L HEMI engines, including Hellcat.  Part # 61119 (complete single) or # 61109 (bare single) thru Marken Performance come equipped with springs for use in hydraulic roller camshaft applications with 73cc chamber size for your 6.1L, 6.2L, 6.4L HEMI engines.  Call Marken Performance for 5.7L applications and other chamber size applications. 
   These cylinder heads have been machined to be used on either the driver or passenger side of the block.  These cylinder heads feature fully CNC machined combustion chambers along with CNC profiled bowls and port entries/exits for improved air flow.  They also feature more material in the deck and reinforced combustion chambers for increased cylinder pressures.  The rocker bosses have been reinforced for improved stability and strength.  Extra material has been added around the intake and exhaust ports to allow for more porting in racing applications.  Both the intake and exhaust port flanges have remained in the factory location for use with OEM components.  The intake and exhaust valves have been tipped away from the bore wall to unshroud the larger valves, while maintaining factory geometry.  The seat diameters have also been increased for improved heat transfer and durability over stock.  Compatible with stock valve covers and ignition coils. 
   Some specs: Intake valve diameter is 2.165";  Exhaust valve diameter is 1.650";  Valve spring maximum lift .690". 

   

 
   For even better flow use Edelbrock Victor EFI # 7179 Black Intake Manifold for  5.7L, 6.1L and 6.4L Gen III HEMI engines.  The overall design is similar to the factory 6.1L SRT intake manifold, but features relocated fuel injector bosses for improved flow and added nitrous bosses along the near vertical runners.  The front inlet can accommodate the factory style 84mm throttle body or the 92mm Hellcat throttle body.  In testing, it made 25 hp over the stock intake manifold on a 6.4L engine.  This manifold will clear most hoods without modifications. Fuel rail kit # 3647 available separately.
