Edelbrock has announced the release of its much-anticipated Performer RPM cylinder head for 2003-Present Gen III HEMI engines.

The Edelbrock Performer RPM is a bolt-on performance upgrade for 2003-Present Gen III HEMI 5.7L, 6.1L, 6.2L and 6.4L engines. It’s designed with the Eagle intake and exhaust port location and can be used with the 5.7L Eagle and later stock intake manifold, exhaust manifolds, valve covers, rockers, spark plugs and accessories, as well as Hellcat components. These cylinder heads have been machined to be used on either the driver or passenger side of the block.

This cylinder head features fully CNC machined combustion chambers along with CNC profiled bowls and port entries/exits for improved air flow. It also features 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 porting in racing applications. The intake and exhaust valves have been tipped away from the bore wall to accommodate the larger valves, while maintaining compatibility with OEM valvetrain components. The seat diameters have also been increased for improved heat transfer and durability.
