The Mopar MN1038 cylinder head is a direct replacement for the factory cast-iron heads, but with significant performance enhancements.

Additionally, the Mopar MN1038 cylinder heads come with a performance-tuned port design. The ports have been carefully crafted to provide optimal flow and velocity, ensuring that the fuel-air mixture is delivered efficiently to the combustion chamber. The result is a more powerful and responsive engine.

The Mopar MN1038 cylinder heads are designed to work seamlessly with your existing engine components, making installation straightforward. They come with new valvesprings, retainers, and other necessary hardware, ensuring that your installation goes smoothly.

In summary, the Mopar MN1038 Big Block Cast Performance cylinder heads are an excellent upgrade for any 1964-1976 Chrysler, Plymouth, or Dodge vehicle.
