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.

When you design and sell the best-engineered performance products in the world, you have to have a rigorous testing program. Why? Without adequate testing, there's no way to stand behind your product with confidence. That's why every product we design and sell at Edelbrock is tested and approved by Edelbrock engineers in a real world environment on state-of-the-art equipment. Our three Super Flow computerized engine dynos are capable of measuring 11 separate engine variables up to speeds of 12,000 rpm. For 2007, we added a new Super Flow SF902 engine dyno. It's fully automated and programmable to simulate various driving situations, and is equipped with WinDyn software for the very latest in testing equipment. For real-world tuning, there's our Super Flow model SF-840 eddy-current chassis dyno that can handle up to 1,000 hp at the wheels and speeds of 200 mph. When all testing is completed, the results evaluated, and the part has passed all performance criteria, then, and only then, is the product deemed ready for production. These precise testing procedures are applied to the entire Edelbrock line for performance that's guaranteed. Edelbrock test vehicles are driven by Edelbrock engineers and employees to get a "real world" feeling for the performance improvements. Our products are also tested and used by professional race car teams and drivers. Working with these talented individuals is just another extension of our research and development process so when we say "proven performance" we really mean it! Top racing teams in all forms of motorsports rely on Edelbrock to produce parts that they can count on to win races and championships. Further underscoring our commitment to the racing community, Edelbrock is the only aftermarket intake manifold manufacturer licensed by NASCAR.
