Edelbrock Group continues to lead the charge in crafting high-quality products tailored for GEN III Chrysler and Dodge HEMI® engines showcased at this year’s Specialty Equipment Market Association (SEMA). They’ve unveiled an exciting addition: an enhanced iteration of their acclaimed Performer RPM cylinder heads, compatible with both O.E.M. 15-bolt and aftermarket 23-bolt engine blocks for GEN III HEMI® engines.
These meticulously engineered cylinder heads are primed for top-notch performance right out of the box, boasting as-cast intake and exhaust ports designed to optimize airflow. These ports seamlessly align with the OEM specifications for the 6.4-liter (392 cubic-inch) HEMI® “Apache” V8. They can also accommodate the 5.7-liter (345 cubic-inch) HEMI “Eagle,” 6.1-liter (370 cubic-inch) HEMI SRT V8, and 6.2-liter (376 cubic-inch) HEMI® “HELLCAT” intake manifold. Serving as a premium replacement head suitable for any high-performance application, these heads deliver unparalleled performance value within the GEN III HEMI® engine platform.
This cylinder head comes assembled with top-of-the-line COMP Cams valve train components, including Beehive valve springs, chromoly steel retainers, robust stainless-steel valves, and high-quality valve seals — all meticulously assembled and inspected by proficient Edelbrock technicians. The Beehive valve springs can accommodate camshafts with lifts up to .680”, making them an excellent fit for a range of camshaft profiles, from mild to high-performance. The integrated truss design additionally provides stability to the valve train during high RPM operation.
Manufactured in San Jacinto, California, using premium materials and machined to the industry’s most exacting standards, these Edelbrock Performer RPM heads guarantee consistent performance in every cylinder head. Special attention is given to maintaining precise tolerances on valve seat concentricity, and they’re equipped with high-grade manganese bronze valve guides for extended durability, ensuring secure valve sealing and minimizing leak-down while enhancing cylinder pressure during engine operation.
Edelbrock’s patented Clean Cast Technology™ takes center stage, a groundbreaking process that eliminates casting imperfections and promotes a smoother internal surface finish for enhanced air and coolant flow. These advantages translate to increased power output and improved cooling capabilities right out of the box.
The latest addition to the lineup, the GEN III HEMI Performer RPM heads, comes with part number 61135 and is priced at $1,395.95.
