    Edelbrock 61649 - Edelbrock Cobra-Jet Performer RPM & Victor Heads Details

    Ford 429-460ci Performer RPM Aluminum Cylinder Heads

    Features:

    • Complete heads feature stainless steel 2.19'' intake and 1.760'' exhaust ''tulip-head'' valves with 11/32'' stems in Serdi-machined ductile iron seats, heavy-duty 1.540'' valve springs that can handle valve lift up to .700'', guideplates, steel retainers, keepers and bronze valve guides.
    • Victor Jr. 460 CJ heads include titanium retainers and roller cam valve springs.
    • 75cc combustion chambers that yield 9.5:1 compresson on Ford SVO 514 CJ crate engine for 624hp potential on the street with 92 octane gas.
    • Port matched intake ports deliver optimum flow and are in the stock location for compatibility with standard manifolds.
    • High-flow, port matched exhaust ports are in the stock location.
    • Rocker stud mounting holes and exhaust bolt holes are heli-coiled for strength.
    • 5/8'' thick deck surface for maximum gasket retention.
    • Made of A356 aluminum and heat treated to a T-6 spec.

      Tech Tip: To gain more spark plug clearance, Edelbrock recommends using Champion RC Series plugs such as the RC12YC (P/N 192-49776). They are 0.230'' shorter than a conventional spark plug and have a 5/8'' hex for easier access.
