Edelbrock Performer RPM Cylinder Head for Gen III HEMI Engines

Torrance, CA - {July 26, 2017}
Edelbrock is excited to announce 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.

They one thing I would like to know is can they fit a dual valve spring. A 2.165 stainless valve would be very heavy for a behive

The spring retainer needs to be lower on the stem to clear stock rockers also.

I would like to see spring seats and bowl areas.

Why did you buy them bare?

Here are some pics of the heads. I bought them bare so we could try a few things with them. One nice thing is they come with no valve job so you have material to work with.

So i wonder if a dual spring fits over that big step on the spring seat. Port looks either wide or pushrod pinch has more material. The bowl looks nice
