Buying Guide For Best 23-Degree SBC Heads
First, the type of head you select will largely depend on your vehicle’s engine and the power gains you are trying to achieve. If you’re looking to maximize power output, aluminum heads often provide the best results, as they are more lightweight and provide more efficient cooling. If you’re working with a tighter budget, cast iron heads are also an option.
Second, the choice of port shape will play a role in engine efficiency, so it’s important to select heads that offer an ample port size for the displacement of your engine. If you plan to perform basic porting and/or flow testing on the heads, it’s essentials to also consider accessibility to the ports and other areas.
Third, the valve angle is also an important factor. A 23-degree valve angle is optimal for most applications, offering excellent volumetric efficiency and airflow without compromising the reliability of your engine.
Finally, it’s important to consider the quality of the heads when shopping around. Check for casting flaws and other indications of a weak or poorly-made head. A good set of 23-degree heads should come with at least one year of manufacturer’s warranty.
Now that you know what to look for in 23-degree SBC heads, you can easily find a set that’s right for your vehicle and engine setup.
