Edelbrock 62055 Features:

Edelbrock introduces the new Performer RPM 205 cc Cylinder Heads for Gen I Small-Block Ford engines. Designed as the ideal next-step upgrade from Edelbrock’s Performer series, these premium cylinder heads offer increased airflow, exceptional quality, and compatibility with a wide range of performance components. Manufactured in Edelbrock’s ISO-certified facility in San Jacinto, California, each cylinder head is machined to exacting tolerances to ensure superior performance and reliability. With larger 205 cc intake ports than comparable Performer RPM heads, these heads are specifically engineered for applications that demand increased performance while maintaining compatibility with off-the-shelf parts. They are suitable for any 289, 302, or 351W engine that does not require meeting emission standards, making them a perfect choice for street and strip builds. Each Performer RPM 205 cc cylinder head is fully assembled with high-quality valvetrain components, including stainless steel one-piece swirl-polished intake and exhaust valves with undercut stems for increased flow, 2-ring positive oil control seals, 3/8" rocker arm studs with 5/16" guide plates, hardened steel valve spring locators, and Edelbrock Sure-Seat valve springs, retainers, and keepers. Edelbrock’s patented Clean-Cast™ Technology eliminates internal casting flaws, producing smoother internal surfaces to improve airflow and coolant flow. This advanced manufacturing process yields greater power potential and enhanced cooling performance right out of the box. Engineered for high-performance builds, the Performer RPM 205 cc Cylinder Heads deliver exceptional value and power gains for enthusiasts building or upgrading Small Block Ford engines.

Edelbrock’s Performer RPM 205 cc Cylinder Heads boost airflow and performance for Gen I Small-Block Ford engines. With precision 205 cc ports, premium machining, and full parts compatibility, they’re ideal for 289, 302 & 351W builds.
