1966 Cylinder Heads

A damaged or cracked cylinder head can cause your 1966 Mustang to lose power, or stop running entirely. When you go to rebuild, you'll have many great cylinder head options. Even if your engine is still functioning brilliantly, it may be worth checking out some of the cylinder head options available for your classic Mustang.

Maintain Your Mustang's Power

When shopping for new cylinder heads, most people focus on the airflow measurements. This is obviously an important part of the equation. In particular, you'll want to pay attention to the intake volume. While some cylinder head manufacturers focus exclusively on flow bench numbers, high-quality brands like Edelbrock, Ford Performance, and Air Flow Research will also do real-world testing. That means that the performance numbers you see will also translate to your every day use.

While it can be tempting to just look for the largest numbers, aspects like low-end torque and throttle response will also affect your overall satisfaction with your engine. Some small ported cylinder heads are worth considering when you factor in all of the additional ways they improve performance.

Picking cylinder heads can feel overwhelming since it's such an important part of your engine build. But that's why we've curated these selections. Whether you just want to return to factory-fresh performance or want to get the benefits of modern technology in your first-gen Mustang, we've got options that'll fit your build.
