{"product_id":"rpm-small-block-ford-2-08-205cc-cyl-head-hydraulic-roller","title":"RPM Small-Block Ford 2.08\"  205cc Cyl Head Hydraulic Roller","description":"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.\r\n\u003cul\u003e\t\u003cli\u003e205cc intake ports for more airflow over OEM designs\u003c\/li\u003e\r\n\t\u003cli\u003eLarger valve spring for better valve control and higher lift camshafts\u003c\/li\u003e\r\n\t\u003cli\u003eOEM intake and exhaust port locations for maximum OEM and aftermarket manifolds and accessories\u003c\/li\u003e\r\n\u003c\/ul\u003e\r\n\r\n\u003cb\u003eVehicle Specific\u003c\/b\u003e\r\n\u003cul\u003e\r\n\u003cli\u003eFord 289, 302, 351W\u003c\/li\u003e\r\n\u003cli\u003eFord Windsor Engine Platform\u003c\/li\u003e\r\n\r\n\u003c\/ul\u003e\r\n\u003ch3\u003eAttributes:\u003c\/h3\u003e\r\n\u003cp\u003e\u003c\/p\u003e\u003cul\u003e\r\n\u003cli\u003e\n\u003cb\u003eBrand Name: \u003c\/b\u003eEdelbrock\u003c\/li\u003e\r\n\u003cli\u003e\n\u003cb\u003eGTIN: \u003c\/b\u003e00085347899654\u003c\/li\u003e\r\n\u003cli\u003e\n\u003cb\u003eCNC Machined Exhaust Port: \u003c\/b\u003eNo\u003c\/li\u003e\r\n\u003cli\u003e\n\u003cb\u003eCNC Machined Intake Port: \u003c\/b\u003eNo\u003c\/li\u003e\r\n\u003cli\u003e\n\u003cb\u003eCNC-Machined Combustion Chamber: \u003c\/b\u003eNo\u003c\/li\u003e\r\n\u003cli\u003e\n\u003cb\u003eCNC-Machined Exhaust Runner: \u003c\/b\u003eNo\u003c\/li\u003e\r\n\u003cli\u003e\n\u003cb\u003eCNC-Machined Intake Runner: \u003c\/b\u003eNo\u003c\/li\u003e\r\n\u003cli\u003e\n\u003cb\u003eCombustion Chamber Volume: \u003c\/b\u003e60\u003c\/li\u003e\r\n\u003cli\u003e\n\u003cb\u003eCylinder Head Style: \u003c\/b\u003eAssembled\u003c\/li\u003e\r\n\u003cli\u003e\n\u003cb\u003eExhaust Port Location: \u003c\/b\u003eStandard\u003c\/li\u003e\r\n\u003cli\u003e\n\u003cb\u003eExhaust Port Shape: \u003c\/b\u003eSquare\u003c\/li\u003e\r\n\u003cli\u003e\n\u003cb\u003eExhaust Runner Volume: \u003c\/b\u003e62\u003c\/li\u003e\r\n\u003cli\u003e\n\u003cb\u003eExhaust Valve Angle: \u003c\/b\u003e20\u003c\/li\u003e\r\n\u003cli\u003e\n\u003cb\u003eExhaust Valve Diameter: \u003c\/b\u003e1.6\u003c\/li\u003e\r\n\u003cli\u003e\n\u003cb\u003eExhaust Valve Job Diameter: \u003c\/b\u003e1.6\u003c\/li\u003e\r\n\u003cli\u003e\n\u003cb\u003eExhaust Valve Stem Diameter: \u003c\/b\u003e0.3438\u003c\/li\u003e\r\n\u003cli\u003e\n\u003cb\u003eGuide Plates Included: \u003c\/b\u003eYes\u003c\/li\u003e\r\n\u003cli\u003e\n\u003cb\u003eGuide plate Pushrod Size: \u003c\/b\u003e5\/16\u003c\/li\u003e\r\n\u003cli\u003e\n\u003cb\u003eIntake Port Location: \u003c\/b\u003eStandard\u003c\/li\u003e\r\n\u003cli\u003e\n\u003cb\u003eIntake Port Shape: \u003c\/b\u003eRectangle\u003c\/li\u003e\r\n\u003cli\u003e\n\u003cb\u003eIntake Runner Volume: \u003c\/b\u003e205\u003c\/li\u003e\r\n\u003cli\u003e\n\u003cb\u003eIntake Valve Angle: \u003c\/b\u003e20\u003c\/li\u003e\r\n\u003cli\u003e\n\u003cb\u003eIntake Valve Diameter: \u003c\/b\u003e2.08\u003c\/li\u003e\r\n\u003cli\u003e\n\u003cb\u003eIntake Valve Job Diameter: \u003c\/b\u003e2.08\u003c\/li\u003e\r\n\u003cli\u003e\n\u003cb\u003eIntake Valve Stem Diameter: \u003c\/b\u003e0.3438\u003c\/li\u003e\r\n\u003cli\u003e\n\u003cb\u003eMaterial: \u003c\/b\u003eAluminum\u003c\/li\u003e\r\n\u003cli\u003e\n\u003cb\u003eQuantity: \u003c\/b\u003eSingle\u003c\/li\u003e\r\n\u003cli\u003e\n\u003cb\u003eRelated Products: \u003c\/b\u003e7181-Performer RPM Small Block Ford Intake Manifold 7227-Exhaust Manifold Gasket Set for Ford 7560-Valve Cover Gasket Set for Ford 1076-Edelbrock high quality RTV silicone 3 oz OE silicone gaskets 85522 - Bolt Kit\u003c\/li\u003e\r\n\u003cli\u003e\n\u003cb\u003eRequired Products: \u003c\/b\u003e7220-Intake Manifold Gasket for Hardened pushrods required.
