The 428ci heads feature large, high-flow combustion chambers, designed to accommodate a generous amount of fuel and air for a powerful combustion event. The increased volume of the combustion chambers is coupled with a high-lift, high-duration camshaft profile that ensures a rapid intake and exhaust stroke, further boosting engine output.

This design reduces backpressure within the engine, ensuring that exhaust gases can exit the engine as quickly as possible, further improving engine efficiency and power.
The 428ci heads are also equipped with high-quality valves and springs, designed to withstand the increased pressures and temperatures produced by high-performance applications. The valves are made from a durable, heat-resistant material, while the springs are designed to provide a precise valve lift for optimal performance.
In addition, the 428ci heads are finished with a bright, polished appearance that not only looks great but also helps to reduce engine heat by reflecting away excess heat. This not only makes your engine look great but also helps to maintain optimal operating temperatures, ensuring long-term reliability and durability.
Overall, the 428ci heads are a high-performance upgrade for any 1969 Pontiac GTO or other Air 400 RAM-equipped model. They provide a significant increase in power and efficiency, while also improving engine reliability and durability.
