Edelbrock E-Street Small-Block Heads (2.02″)
The Edelbrock E-Street cylinder heads are designed to complement Ford small-block and big-block builds with efficient flow characteristics. These complete pair heads deliver a 60cc combustion chamber and 170cc intake/60cc exhaust runner volumes, offering solid performance gains on street or weekend race applications. The kit is well-suited for enthusiasts aiming to improve air flow without major engine modifications, and it pairs well with existing Edelbrock components for a cohesive setup.
Ford Super Cobra Jet Bare Head
This aluminum cylinder head is tailored for big block Ford engines, offering a 72 cc combustion chamber and larger intake port features. The Super Cobra Jet head is suitable for performance-focused builds that require robust airflow and reduced weight compared to iron equivalents. While installation may necessitate compatible manifold and valve train considerations, its design supports higher compression and improved combustion efficiency in the right combination with other performance parts.
IMOOA Bare Cylinder Head For Ford Small Block
The IMOOA bare cylinder head is compatible with Ford Small Block 289, 302, 351W, and 5.0L V8 engines. It features a 2.020 inch intake valve diameter and a 1.600 inch exhaust valve diameter, aligning with common performance upgrades. Aluminum construction helps reduce weight while improving heat dissipation. This head supports custom porting and valve train upgrades for enthusiasts pursuing tailored airflow improvements and higher horsepower potential.
AMVirtuo Shorty Exhaust Headers For Ford Big Block
Although primarily a headers option, these shorty stainless steel headers are relevant for big-block Ford builds by improving exhaust flow and reducing backpressure, which can maximize head performance when paired with compatible heads. They are designed for 1968-1977 Ford Big Block engines (429/460/7.0L). The mandrel-bent 304 stainless steel resists rust and heat, while TIG-welded seams ensure seal integrity under high exhaust temperatures. This choice complements high-flow heads for a well-rounded setup.
Flotek 203505 Aluminum Cylinder Head
The Flotek 203505 aluminum cylinder head is designed to support small block Ford platforms with an emphasis on lighter weight and efficient airflow. While targeted at smaller displacements, the aluminum construction offers improved cooling characteristics and potential horsepower gains when paired with an appropriate intake and cam setup. This head is a good option for builders seeking a balance between performance and weight reduction in mixed Ford engine classes.
Cylinder Head Gasket Set (18mm) For 6.0 Powerstroke Diesel
This gasket set targets diesel applications (6.0L Powerstroke) and, while not a direct big block Ford head product, it highlights the gasket and seal considerations that accompany high-performance head swaps. When planning a head upgrade, ensuring compatible head gaskets, bolts, and sealing strategies is essential to prevent leaks under increased cylinder pressure and elevated engine temperatures.
JEGS Engine Gasket Kit For Ford Big Blocks
The JEGS gasket kit is tailored for most 1968-1987 Ford 429-460 big block engines, excluding Boss, CJ, and SCJ variants. It includes intake port gasket components and other seals necessary for a complete head swap or rebuild. The kit supports reliable sealing and part compatibility during high-stress engine upgrades, helping maintain performance and longevity when combined with upgraded cylinder heads.
Buying Guide: Key Purchase Considerations
- Engine compatibility: Ensure the head design fits your Ford engine family (big block vs. small block, valve sizes, chamber volume).
- Material and weight: Aluminum heads offer lighter weight and better heat dissipation but may require careful mounting hardware and upgraded valvetrain components.
- Chamber size and compression: 60cc vs 72cc chambers influence compression ratio; match with your cam, pistons, and induction for desired performance.
- Flow characteristics: Intake and exhaust runner volumes affect airflow; consider porting potential and compatibility with your intake manifold and headers.
- Support components: Gasket sets, head bolts, and valve train parts must align with your chosen heads to ensure proper sealing and reliability.
- Intended use: Street use, hot-rodding, or track emphasis will guide the balance between performance, durability, and install complexity.
- Cost vs benefit: Compare the overall package—head alone vs. complete kit with gaskets and hardware—to estimate total project cost and performance gains.
- Aftermarket ecosystem: Availability of matching manifolds, cam choices, and block clearances can influence installation feasibility and performance.
