Review MILODON Megaflow Exhaust Valves Pontiac 389 421 fits 350 400 428 455 1971

The Milodon 45495-8 MegaFlow Exhaust Valves are a high-performance upgrade for Pontiac engines with model numbers 350, 389, 400, 421, 428, and 455, particularly those manufactured in 1971. These exhaust valves are designed to deliver enhanced engine performance and improved durability compared to the original equipment.

The MegaFlow Exhaust Valves from Milodon are made from high-quality materials, including a robust stainless steel construction for the valves and seats. This ensures that they can withstand the extreme temperatures and pressures generated within the engine, providing reliable operation even under heavy loads.

These exhaust valves feature a large 2.02-inch (51.3mm) intake valve diameter and a 1.59-inch (40.4mm) exhaust valve diameter, which increases the flow rate of the exhaust gases. The larger valve size allows for a more efficient exhaust flow, reducing backpressure within the engine and enabling a more complete combustion process.

The MegaFlow Exhaust Valves also come with a unique design that includes a recessed valve seat, which helps to prevent carbon build-up and extend the valve life. The valves use a dual-spring design, which ensures consistent valve action and helps maintain proper valve clearance throughout the engine's life.

These exhaust valves also feature a hollow stem design, which reduces the weight of the valve and allows for easier installation. The valves come with new valve guides and seals, ensuring a proper seal and reducing the chances of leaks.

The Milodon 45495-8 MegaFlow Exhaust Valves are an excellent choice for anyone looking to enhance the performance and durability of their Pontiac engine. They offer improved flow rates, extended valve life, and reliable operation, making them a worthwhile investment for enthusiasts and performance builders alike.
