Imagine that you could get the advanced features of Dart's championship-winning aluminum big block heads in a cast-iron version. Now you can at a price that fits every budget!
Dart's Big Block Iron Eagle Cylinder Heads were designed for street performance, bracket racing, oval track competition, tractor pulling, and high-performance marine applications. There are two rectangular ports: a high-velocity 308cc intake runner that produces incredible torque and a 345cc version that's perfect for big-inch, high-RPM Rat motors. The Iron Eagle's raised exhaust port outperforms its cast-iron competition but still fits most standard headers. Dart's dedicated tooling allows ports to be cast with incredible precision so you get maximum flow without spending big bucks on porting. Valve angles are rotated two degrees, and the efficent heart-shaped combustion chambers originally developed for Dart's championship-winning Race Series aluminum heads have been replicated.
Iron Eagle big block heads have standard features you won't find in factory castings and aftermarket replacement heads. Premium bronze valve guides, multi-angle intake valve seats, and hardened and radiused exhaust seats are included with every Iron Eagle head. When you want premium performance at an economical price, demand Dart Iron Eagle Heads.
