Replace your Ford Windsor small blocks stock heads with Dart Iron Eagle cylinder heads for a big performance upgrade at an unbeatable price! They're cast from premium, high-density iron with extra-thick decks for increased durability, plus they have machined valve cover rails and end pads for leak-free performance that fits like stock. Inside, you'll find precision-cast runners and combustion chambers, plus multi-angle intake and radiused, hardened exhaust seats for excellent airflow. The fully assembled heads come complete with screw-in rocker studs, stainless steel valves, valve springs (.550 in. max lift for 1.250 in. springs, .620 in. max lift for 1.467 in. springs), bronze valve guides, steel retainers, locks, and seals.
