IMOOA Ford Aluminum Head For 302/289/351W
The IMOOA bare cylinder head is designed for Ford small-block engines, including the 289, 302, and 351W. It features an 185cc intake runner and a 61cc combustion chamber, aiming to balance power and compression for street and lightCompetition use. The design focuses on compatible valve sizes, with an intake valve diameter of 2.020 inches and an exhaust valve diameter of 1.600 inches, enabling straightforward valve-train planning and port matching. This head is a practical option for builders seeking a Ford-specific aluminum head with a moderate chamber volume.
Auto Dynasty Aluminum Bare Cylinder Head SBC 302/327/350/383/400
This Auto Dynasty head is tailored for Chevrolet small-block engines up to 1986, including 302, 327, 350, 383, and 400. It features a 200cc intake runner and a 68cc chamber, delivering a balance of airflow and compression suitable for classic SBC builds. The square intake and exhaust ports support broad aftermarket intake options, while the chamber design helps retain stock-like compression on older models. It’s a practical choice for builders seeking a cost-effective upgrade with solid airflow characteristics.
DNA Motoring CYLH-SBC-350 Aluminum Head SBC 302/327/350/383/400
The DNA Motoring CYLH-SBC-350 offers a 200cc intake runner with a 68cc combustion chamber, designed for Chevrolet small-block engines 302–1986. The design emphasizes a square intake and exhaust port layout for improved airflow and efficient combustion. Aimed at performance-minded builders, this head aligns with classic SBC architecture while delivering better-than-stock flow for street and moderate-performance builds.
Speedmaster PCE281.2048 Ford SB 289/302 Windsor Heads
Speedmaster’s PCE281.2048 assembly targets Ford small-blocks, including 289, 302, and Windsor variants, with a 190cc intake and a 62cc chamber.

The kit aims to deliver reliable performance across road and racing environments, supporting hydraulic roller setups and straightforward installation for enthusiasts seeking a complete top-end upgrade.
SBC 350 Bare Aluminum Head For 302/327/350/383/400
This bare aluminum head claims compatibility with Chevrolet small-block engines 302, 327, 350, 383, and 400, featuring a 200cc intake runner and a 64cc combustion chamber. The 64cc chamber is selected to provide a balance of compression and performance for 1970s-era SBC builds, while the 200cc intake helps improve airflow. The design emphasizes durable construction with hardened seats and bronze guides, targeting classic performance upgrades for hot rod and street applications.
Buying Guide: How To Choose Aluminum Heads For 302 Projects
Selecting the right aluminum head for a 302-based project requires balancing airflow, chamber volume, port design, and engine management compatibility. Here are key considerations and typical trade-offs to help you compare options across Ford and Chevy platforms.
- Engine platform and compatibility: Confirm whether the head is designed for Ford small-blocks or Chevy SBC applications, and verify compatibility with your specific displacement and year range. Lift limits and valve sizes influence the choice for street versus race builds.
- Airflow vs. compression: Larger intake runners (around 190–210cc) generally improve top-end power but may require compression adjustments or different cam specs. Smaller chambers (around 60–68cc) boost compression but can raise combustion chamber temperatures; ensure the setup remains reliable at your target RPMs.
- Port and valve geometry: Square ports and standard valve diameters ease manifold and header choices. Consider whether the head offers bronze guides, hardened seats, and valve sizes that fit your intended cam and rocker setup.
- Intake compatibility: Check the availability of compatible intake manifolds and gasket profiles. Some heads are paired with specific intake designs, which can affect fitment and seal integrity.
- Finish and reliability: Pay attention to bore quality, casting integrity, and whether seats and guides are pre-installed or require additional machining. Remanufactured or bare heads may need more assembly work but can be cost-effective.
- Street vs race orientation: If you primarily drive on the street, prioritize lower duration cams, reliable cooling, and drivability. For race-oriented builds, larger runners and higher-flow configurations may yield more power at higher RPMs, but require more tuning and supporting components.
- Overall value and build goals: Compare the head’s flow numbers, chamber volume, and port design against your goals (torque-rich low-end, or peak horsepower at high RPM). Pair the head with an appropriate cam, rocker ratio, and exhaust system to realize the predicted gains.
In summary, the best aluminum head for a 302 project depends on your target platform (Ford or Chevy), your desired RPM range, and how much you value ease of installation versus ultimate airflow. The options shown here provide a range of flows, chambers, and compatibility profiles to help you identify a suitable path for your build, from classic street motors to track-ready combinations.
