Product Description

Iron Eagle big block Chevy, 345cc intake runners, 121cc combustion chambers, 2.300 intake and 1.880 exhaust valves, 1.550 dual springs.

We developed 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.

- Valve angles rolled two degrees from stock to reduce chamber volume and improve flow.

- Bolt on compatibility: Works with most off the shelf pistons and valve train components.

- Heart shaped chambers improve combustion efficiency.

- Hardened exhaust seats are compatible with unleaded gasoline.

- Multi-angle intake seats, radius-ed exhaust seats and precision cast valve bowls produce excellent air flow without hand porting or expensive CNC machining.

- Exhaust ports raised .300 to improve flow.

- Manganese bronze intake valve guides ensure long term reliability.

- All cylinder heads sold individually.
