All Iron Heads are DART's New Platinum Series cylinder heads!
The result of three decades of cylinder head development, Iron Eagle heads incorporate features that were previously available only in expensive aluminum cylinder heads. We designed Iron Eagle heads for street performance, bracket racing, oval track competition, and high-performance marine use. We offer five different intake ports - 165cc, 180cc, 200cc, 215cc, and 230cc that cover virtually every engine application. Dart Iron Eagle heads have standard features you don’t get in other factory and aftermarket cast-iron cylinder heads. Long-wearing bronze valve guides (except S/S), multi-angle intake valve seats, and hardened and radiused exhaust seats are standard.
