If you own a 2003 to present Gen III 5.7L, 6.1L, 6.2L Hellcat or 6.4L HEMI engine and have been looking for a power bump, Edelbrock has the answer for you with their wicked Edelbrock Performer RPM cylinder heads. Edelbrock always strives to offer the best products that combine the highest of quality with an easy installation that almost anybody can do themselves. Their RPM cylinder heads are designed to fit with the stock intake manifold, exhaust manifolds, valve covers, rockers, coils, spark plugs and other accessories on all of the modern Gen III HEMI engines, including Hellcats!

These cylinder heads have been machined to be used on either side of the block and are cast from A356 aluminum and heat treated to T6 specifications. For unmatched and guaranteed quality, they are machined and assembled at Edelbrock’s facility in Torrance, California. These cylinder heads feature fully CNC machined combustion chambers along with CNC profiled bowls and port entries/exits for improved air flow. These heads are guaranteed to be a much better than the factory units as they 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. If you are hard core into racing, Edelbrock has added extra material around the intake and exhaust ports to allow for porting in higher horsepower racing applications. Both the intake and exhaust port flanges have remained in the factory location for use with your OEM components. The seat diameters have also been increased for improved heat transfer and durability over stock.

If you want the most of your Gen II HEMI, we strongly suggest matching the heads with an Edelbrock Victor II EFI intake manifold (part# #7179) for the ultimate in performance. You won’t regret it and your HEMI will love you!
