Best Heads For Pontiac 350 FAQs
Are aluminum heads better than cast iron heads for a Pontiac 350?
The answer to this question depends on the specific needs and preferences of the individual. Aluminum heads are generally lighter than cast iron heads, which can improve the overall performance of the engine. They also dissipate heat more effectively, which can lead to improved fuel efficiency and increased horsepower. However, aluminum heads are typically more expensive than cast iron heads, which may be a deterrent for those on a budget. Cast iron heads are typically more durable and can withstand higher temperatures, which can be beneficial for high-performance engines. Ultimately, the decision between aluminum and cast iron heads for a Pontiac 350 should be based on the specific needs of the vehicle and the preferences of the driver. It is recommended to consult with a professional mechanic or engine builder to determine the best option for your specific situation.
Can I use Chevy heads on a Pontiac 350 engine?
No, you cannot use Chevy heads on a Pontiac 350 engine. The reason is that Chevy and Pontiac engines have different head bolt patterns, and the bolt holes on the Chevy heads will not align with the bolt holes on the Pontiac block. Even if you were able to modify the heads to fit the block, you would still face compatibility issues with the intake manifold, exhaust headers, and other components.
It is important to use the correct parts when building an engine, as using the wrong parts can cause poor performance, engine damage, and safety hazards. If you are looking to upgrade your Pontiac 350 engine, there are many aftermarket options available that are specifically designed to work with Pontiac engines. These parts will provide better performance and reliability than trying to use incompatible Chevy parts.
How much horsepower can I gain from upgrading to performance heads on my Pontiac 350?
Upgrading to performance heads on your Pontiac 350 can potentially increase horsepower by up to 100. Performance heads are designed to improve airflow and combustion efficiency, leading to an increase in power output. However, the actual amount of horsepower gain will depend on several factors, such as the specific heads you choose, the condition of your engine, and any other modifications you have made. It's important to note that upgrading to performance heads may also require other modifications to your engine, such as a new camshaft or exhaust system, to fully realize the potential horsepower gain. It's always recommended to consult with a professional mechanic or engine builder before making any significant modifications to your engine.
What are the best aftermarket heads for a Pontiac 350 engine?
When it comes to selecting aftermarket heads for a Pontiac 350 engine, there are several options available in the market. The most popular ones are the Edelbrock Performer RPM, the AFR 190cc, and the Trick Flow High-Port. Each of these heads is designed to improve the engine's airflow, increase horsepower, and enhance the overall performance of the vehicle.
The Edelbrock Performer RPM is a great choice for those looking to boost their engine's performance without sacrificing low-end torque. It features a dual-plane design that offers excellent throttle response and a broad power band. The AFR 190cc is a high-performance cylinder head that is designed for maximum airflow and horsepower. It is ideal for those looking to build a high-revving engine with a focus on top-end power. The Trick Flow High-Port is another excellent option that is designed to deliver maximum airflow and power across the entire RPM range.
Ultimately, the best aftermarket heads for a Pontiac 350 engine will depend on your specific needs and preferences. It's important to do your research, read reviews, and consult with experts to determine which heads will work best for your particular engine build.
What is the difference between 2-barrel and 4-barrel heads for a Pontiac 350?
The difference between 2-barrel and 4-barrel heads for a Pontiac 350 is primarily in the number of barrels or ports that allow fuel and air to enter the engine's combustion chamber. A 2-barrel head has two ports, while a 4-barrel head has four ports. The more ports there are, the more fuel and air can enter the engine, resulting in improved performance and horsepower.
Aside from the number of ports, the design of the heads can also differ. 4-barrel heads typically have larger valves, which allow more air to flow into the engine. They also have larger intake and exhaust runners, which further improve airflow. This results in increased power and torque compared to their 2-barrel counterparts.
However, it's important to note that simply upgrading to a 4-barrel head may not always result in significant improvements. Other factors such as camshaft, carburetor, and exhaust system must also be considered to achieve maximum performance gains.
