Upgrading from a cast iron head to a high-performing and lightweight aluminum head is one of the most effective improvements you can make to your Big Block Ford engine. The best part? It’s now more affordable than ever. Speedmaster's line of Big Block Ford performance heads has consistently delivered exceptional results on the track, in dyno testing, and in features in leading performance magazines.

They offer cylinder heads tailored to a variety of displacement applications, recognizing the growing demand for increased airflow as larger displacement engines become more common. If your goal is to build an engine with 400 to 700 horsepower, Speedmaster Aluminum cylinder heads are an excellent option. Utilizing their "Gravity Die Cast" process, these heads boast superior strength and consistency. Their optimized design also includes a smaller cross-section to enhance air velocity, leading to improved drivability, power, and fuel efficiency.

Speedmaster cylinder heads are available in two configurations: "as-cast" versions for mild street builds and fully CNC-machined versions for serious enthusiasts. The CNC-machined heads are produced using advanced 5-axis machining centers, ensuring precise and cost-effective production. Fully machined combustion chambers and intake and exhaust ports maximize airflow, while CNC-machined chambers offer improved flame control and quench properties. By eliminating human error, CNC porting ensures consistent performance across all ports.
