The Edelbrock Performer RPM Street Cylinder Head is designed for street high performance use, and is interchangeable with any 1968-87 standard (non Cobra-Jet) 429-460 Ford cylinder head. This new cylinder head offers “out of the box” bolt-on performance with no additional porting required. The performance range is 1500-6500 rpm. The intake and exhaust ports are CNC machine “matched” and have been designed for maximum performance when matched with our Performer RPM intake manifold #7166, Performer RPM cam kit #7167, and a Edelbrock Performer Series square-bore carburetor, #1407 (750 cfm), #1412 (800 cfm manual choke), #1413 (800 cfm electric choke) or Performer RPM Q-Jet carburetor #1910 (850 cfm).
A properly sized intake port with the standard inlet flange design yields flow numbers traditionally associated with Cobra-Jet cylinder heads, but with a runner size that provides the correct inlet velocity for great throttle response throughout the power band as well as top-end horsepower. The 460 Ford Performer RPM cylinder head is available in two combustion chamber volumes, 95cc and 75cc, to provide a 460 Ford Performer RPM cylinder head that will match with as many engine combinations as possible. The compact combustion chamber design is made to maximize combustion efficiency and port flow with streetable compression ratios. The Performer RPM 460 cylinder head exhaust flange will accept stock exhaust manifolds or exhaust headers made for stock cylinder heads. NOTE: These cylinder heads have no exhaust crossover passage or AIR passages and will not work on any vehicle requiring EGR or other emissions equipment.
Complete Performer RPM 460 cylinder heads are assembled with the following components: Stainless steel, one-piece, swirl-polished intake and exhaust valves with under-cut stems for increased flow; 2-ring positive oil control seals; 7/16″ rocker studs and 3/8″ guide plates; Edelbrock Sure-Seat Valve Springs #5745, valve spring seats #5770, retainers #9715, and valve keepers #9616. Complete cylinder heads are assembled and prepared for installation right out of the box. Bare cylinder heads will have valve guides and seats installed, but will require final valve guide sizing and a valve job to match the valves you will be using.
