The all-new Victor Jr. Ford heads have a 500+ horsepower potential, out-of-the-box, for an affordable, race-winning set-up. They feature large volume, high-flowing 210cc intake ports and .130' raised 75cc exhaust ports. Designed to work with standard port location manifolds and headers, these heads have CNC gasket-matched port entries and exits with blended valve bowls. The spark plug holes and valves are in the stock location with a valve cover rail that1s raised .150'. Complete heads come with stainless steel, 1-piece, swirl-polished, under-cut stem valve (2.05' intake/1.60' exhaust) as well as phosphor bronze valve guides.Note: Aftermarket 289/302 heads including Brodix, Edelbrock, Ford Motorsport and World Products with 1/2' bolt hole diameters (block is 7/16' bolt hole), except 397-M-6049-P303 ('P' style head). Require 350-9680 inserts with 350-8552 head bolt or 350-9680 insert with 070-154-3601. If head studs are desired use 070-154-4005 (includes inserts).
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.
