Review PONTIAC Cylinder Head Pair Casting Remanufactured fits 350

The Pontiac J280 Cylinder Head 350 is a high-performance upgrade for your classic Pontiac engine. This cylinder head is designed specifically for the 350 cubic inch V8 engine, commonly found in popular Pontiac models like the GTO, Grand Prix, and Firebird.

The J280 cylinder head features a unique CNC porting design that maximizes airflow and fuel delivery, resulting in improved combustion and increased horsepower. The ports are radiused and polished to a mirror finish, ensuring optimal fluid dynamics and promoting a more efficient fuel-air mixture.

The cylinder head is made from high-quality aluminum alloy, which is lightweight yet incredibly strong. This material provides excellent heat dissipation, keeping the engine cool and preventing overheating during high-performance driving. The head is also equipped with four-bolt main caps and heavy-duty valve springs for enhanced durability and reliability.

The J280 cylinder head also features a unique intake and exhaust port configuration. The intake ports are sized to fit a variety of intake manifolds, while the exhaust ports are designed for optimum exhaust flow. This configuration allows for a more efficient exhaust gas scavenging, reducing back pressure and further enhancing horsepower.

The cylinder head is also equipped with new, larger valves. The intake valves are 2.025 inches, while the exhaust valves are 1.600 inches. These larger valves allow for a greater volume of air and fuel to flow into the cylinders, resulting in increased power and torque.

In summary, the Pontiac J280 Cylinder Head 350 is a high-performance upgrade for your classic Pontiac engine. It features a unique CNC porting design, high-quality aluminum alloy construction, and a new, larger valve configuration to maximize horsepower and torque. With its superior airflow and heat dissipation capabilities, this cylinder head is the perfect choice for any Pontiac enthusiast looking to take their car to the next level.
