New at Summit Racing: Edelbrock Performer RPM Cylinder Heads for Chrysler GEN III Hemi

Help your 2003-up Hemi-powered vehicle breathe better with a pair of Edelbrock’s Performer RPM aluminum cylinder heads. They feature fully CNC-machined 73cc combustion chambers, with CNC-profiled bowls and port openings for improved airflow. 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.

Edelbrock added material in the deck and combustion chamber areas to handle increased cylinder pressures when using a turbo or supercharger. The rocker bosses have been reinforced for improved stability and strength, and extra material has been added around the intake and exhaust ports to allow for porting. The heads also fit either side of the block—no worries about remembering proper orientation.

The Performer RPM GEN III cylinder heads are compatible with the stock intake manifold, exhaust manifold, valve cover, rockers, spark plugs, and accessories, and can be used with Dodge Charger/Challenger Hellcat components. Assembled heads come with valves, valve springs, locks, and retainers. Bare castings are also available.
