Best Small Block Chevy Cylinder Heads FAQs
How do small block Chevy cylinder heads affect engine compression ratio and fuel economy?
Small block Chevy cylinder heads can affect engine compression ratio and fuel economy in several ways. Firstly, the combustion chamber design and size of the cylinder head can impact the compression ratio, which is the ratio of the volume above the piston at bottom dead center to the volume above the piston at top dead center. A larger combustion chamber will reduce the compression ratio, while a smaller chamber will increase it. This can affect fuel economy and power output, as higher compression ratios can lead to more efficient combustion and better performance.
Secondly, the airflow characteristics of the cylinder head can impact fuel economy and power output. A well-designed cylinder head with good airflow can result in better fuel efficiency by allowing the engine to breathe more efficiently. Additionally, the valve size and lift can also affect airflow and fuel economy, with larger valves and more lift generally resulting in better performance but lower fuel economy. Overall, the design and specifications of small block Chevy cylinder heads can have a significant impact on engine performance and fuel economy.
How do the airflow characteristics of small block Chevy cylinder heads impact engine performance?
The airflow characteristics of small block Chevy cylinder heads have a significant impact on engine performance. The design of the cylinder head affects the amount of air that can flow through the engine, which in turn affects the combustion process and power output. A well-designed cylinder head will promote efficient airflow and allow the engine to breathe easier, resulting in increased horsepower and torque. The shape of the ports and valves, as well as the size and shape of the combustion chamber, all play a role in determining the airflow characteristics of the cylinder head. Additionally, factors such as compression ratio, camshaft profile, and intake manifold design must also be considered when optimizing the airflow characteristics of the engine. Overall, careful consideration of the cylinder head design is essential for achieving maximum engine performance.
What are the benefits of using aftermarket small block Chevy cylinder heads compared to stock heads?
Aftermarket small block Chevy cylinder heads offer several benefits over stock heads. Firstly, they usually have larger ports and valves, which allow for better airflow and increased horsepower. Secondly, they are often made from better materials, such as aluminum, which reduces weight and improves heat dissipation. Thirdly, aftermarket heads may feature improved combustion chambers and valve angles, leading to better fuel efficiency and power delivery. Additionally, they may have stronger valve springs and retainers, allowing for higher RPMs and better durability. Finally, aftermarket heads offer more customization options, such as different port shapes and sizes, allowing for precise tuning to match specific engine setups and performance goals. Overall, using aftermarket small block Chevy cylinder heads can significantly improve engine performance, making them an attractive option for performance enthusiasts and racers.
What are the best small block Chevy cylinder heads for high-performance engines?
The best small block Chevy cylinder heads for high-performance engines are the ones that offer good airflow, combustion efficiency, and durability. Some of the top options for small block Chevy cylinder heads include the AFR 195cc, 210cc, and 220cc heads, the Edelbrock E-TEC 170cc, 180cc, and 200cc heads, and the Dart Pro 1 180cc, 200cc, and 215cc heads.

They also feature high-quality materials and construction for improved durability and reliability. When choosing the best cylinder heads for your high-performance engine, consider your specific needs and goals, as well as your budget, to make the right decision.
What are the differences between cast iron and aluminum small block Chevy cylinder heads?
Cast iron and aluminum small block Chevy cylinder heads have several differences. Cast iron heads are typically heavier and retain heat longer than aluminum heads. This can be an advantage in colder climates, where heat retention can help the engine warm up faster. However, in warmer climates, aluminum heads are preferred because they dissipate heat faster, helping to prevent engine overheating. Aluminum heads are also usually more expensive than cast iron heads, but they offer better performance due to their lighter weight and improved airflow. Cast iron heads are often stronger and more durable than aluminum heads, but they are more prone to cracking under extreme conditions such as high horsepower or high RPMs. In contrast, aluminum heads are more prone to warping under extreme conditions. The choice between cast iron and aluminum heads ultimately depends on the intended use of the engine and the preferences of the builder.
