If you are a car enthusiast or a mechanic, you might be looking for a set of heads for your Pontiac 350 engine. The cylinder heads are a fundamental part of the engine, and they play a crucial role in the performance and power output of your vehicle. Therefore, it is essential to choose the right set of heads that meet your specific needs and preferences.
Here are five key points that you should consider when looking for heads for your Pontiac 350:
1. Compatibility: Make sure that the heads you choose are compatible with your Pontiac 350 engine. Not all heads are suitable for all engines, so it's important to check the manufacturer's specifications and recommendations.
2. Material: Heads can be made of different materials, such as aluminum, cast iron, or steel. Each material has its advantages and disadvantages in terms of weight, durability, and heat dissipation.
3. Port design: The port design and size of the heads affect the airflow and fuel mixture in the engine. Different port designs can improve low-end torque or high-end power, depending on your driving style and goals.
4. Compression ratio: The compression ratio is the ratio of the volume of the combustion chamber when the piston is at the bottom of its stroke to the volume when it is at the top. Heads with different chamber volumes can change the compression ratio and affect the engine's performance and fuel efficiency.
5. Budget: Heads can range from a few hundred to several thousand dollars, depending on the brand, material, and features. Consider your budget and prioritize the features that are most important to you.
In summary, when looking for heads for your Pontiac 350 engine, you should consider compatibility, material, port design, compression ratio, and budget. By doing so, you can find the best set of heads that suit your needs and improve your engine's performance and power output.

Best Heads For Pontiac 350 FAQs
Can I use Chevy heads on a Pontiac 350 engine?
No, Chevy heads cannot be used on a Pontiac 350 engine. Although both engines share similar displacement, they have different head bolt patterns and different valve angles. Chevy heads have a 23-degree intake valve angle, whereas Pontiac engines have a 14-degree intake valve angle. Moreover, the combustion chambers on Chevy heads are smaller, which can lead to decreased engine performance and power output on a Pontiac engine. It is crucial to use the proper heads designed for the specific engine to ensure optimal performance and reliability. Attempting to use incompatible parts can cause significant damage to the engine and should be avoided. Therefore, it is recommended to use Pontiac heads on a Pontiac 350 engine instead of Chevy heads.
How much horsepower can I expect from Pontiac 350 heads with the right setup?
If you're looking to upgrade your Pontiac 350 engine, the heads you choose can have a significant impact on the horsepower output. With the right setup, you can expect to achieve up to 400 horsepower from Pontiac 350 heads.
The key to achieving maximum horsepower is to choose the right components and make sure they work together seamlessly. This means selecting high-quality, performance-oriented parts such as pistons, camshafts, and carburetors.
In addition to selecting the right components, proper tuning is also critical. This includes setting the timing, fuel delivery, and ignition system to optimize performance.
Overall, with the right combination of parts and tuning, Pontiac 350 heads can deliver impressive horsepower gains. However, it's important to work with a skilled mechanic or engine builder who can help you select the right components and ensure proper installation to achieve the best results.
What are the best aftermarket heads for a Pontiac 350 engine?
When it comes to selecting the best aftermarket heads for a Pontiac 350 engine, there are various options available in the market. One of the most popular choices is the Edelbrock Performer RPM heads, which are designed to offer improved flow and power compared to the original heads. These heads feature a unique design that allows for better air and fuel mixture, leading to enhanced performance.
Another excellent option is the Brodix IK 200 heads, which are known for their superior construction quality and durability. These heads are designed to offer better flow and power than the stock heads and can handle high horsepower levels without any issues.

What is the difference between Pontiac 350 heads and other Pontiac engine heads?
Pontiac 350 heads are specific to the Pontiac 350 engine and differ from other Pontiac engine heads in a few ways. Firstly, they have smaller combustion chambers, which results in a higher compression ratio and increased horsepower. Secondly, they have smaller intake and exhaust ports, which helps to increase the velocity of the air/fuel mixture and exhaust gases, respectively. This can improve low-end torque and throttle response. Additionally, Pontiac 350 heads feature smaller valves than some other Pontiac engine heads, which can limit their potential for high-end horsepower. Overall, the differences between Pontiac 350 heads and other Pontiac engine heads come down to their design and intended use. It's important to choose the right heads for your engine build, depending on your goals for performance and driving style.
What is the ideal compression ratio for Pontiac 350 heads?
The ideal compression ratio for Pontiac 350 heads can vary depending on a number of different factors, including the engine's intended use and the fuel that will be used. However, generally speaking, a compression ratio of around 9:1 to 10:1 is considered to be a good starting point for most Pontiac 350 engines. This range should provide a good balance between performance and reliability, while also allowing for good fuel economy and reasonable emissions levels. Of course, if you are building a high-performance engine or plan to use racing fuel, you may want to consider a higher compression ratio, but this can also increase the risk of engine damage and other issues. Ultimately, the best compression ratio for your Pontiac 350 will depend on your specific needs and goals, so it is important to work with a knowledgeable engine builder or mechanic to determine the right setup for your engine.
