AMC Performer Cylinder Head - Assm.

The Edelbrock Performer Cylinder Head – Assembled for AMC V8 engines delivers a purpose-built foundation for high-performance engine builds. This aluminum cylinder head assembly combines proven Performer RPM architecture with optimized flow characteristics, making it a core component for builders targeting increased horsepower and torque output in classic and modern AMC-powered vehicles.

Key specifications include 2.020-inch intake and 1.600-inch exhaust valve diameters, a 185 cc intake runner volume, and a 54 cc combustion chamber. The 1.550-inch valve spring diameter supports higher rpm operation while the angle-plug design optimizes spark plug positioning for consistent ignition. Edelbrock's assembled approach eliminates the variable of hand-assembly quality, reducing failure points common in budget builds. The aluminum construction balances thermal properties with weight savings, critical for applications where sustained power delivery and engine bay heat management impact reliability.

This head is engineered for AMC V8 engine platforms—the 258, 304, 360, and 401 cubic inch variants. It serves enthusiasts rebuilding vintage Javelins, Ramblers, and Hornets, as well as modern restomod projects that demand factory-compatible bolt-on performance. The Performer RPM line bridges budget and pro-level components, offering flow improvements and chamber consistency without requiring full engine bay redesign or exotic fuel requirements.

Each head ships fully assembled and ready to install, reducing build time and eliminating assembly variables. Weight of 33.05 lbs per head should be factored into vehicle dynamics and suspension tuning for serious competition or high-performance street builds. Pair this with compatible intake manifolds, exhaust systems, and cam packages to realize the designed performance envelope.
