How To Upgrade SBC Heads

 Understanding Stock Sbc Heads

Understanding Stock SBC Heads is essential for anyone who wants to improve the performance of their small-block Chevy engine. These heads are the factory heads that come with most small-block Chevy engines, and they are designed to provide adequate performance for most applications.

However, if you want to increase the horsepower and torque of your engine, upgrading the stock heads can be a good option. Stock SBC heads are usually made of cast iron and have small combustion chambers that limit airflow.

Upgrading to aftermarket heads with larger ports and valves can significantly increase airflow, allowing for more horsepower and torque. However, before making any upgrades, it is important to understand the specifications of your engine and the compatibility of the new heads.

Additionally, upgrading the heads may require other modifications to the engine, such as changing the camshaft, intake manifold, and exhaust system. Therefore, it is important to consider the overall cost and complexity of the upgrade before starting.

 Why Upgrade Sbc Heads?

Upgrading your SBC (Small Block Chevy) heads can be a worthwhile investment for a number of reasons. Firstly, it can improve the performance of your engine by increasing horsepower and torque.

This is because upgraded heads often have better airflow, leading to increased combustion efficiency and power output. In addition, better quality materials and construction can also improve overall engine reliability and longevity.

Upgrading your SBC heads can also be a cost-effective alternative to purchasing a new engine altogether, as it can often provide similar performance gains at a fraction of the cost.

Another benefit of upgrading your SBC heads is the ability to customize and tailor the performance of your engine to your specific needs and preferences. With various options available, from different valve sizes and shapes to various port configurations, you can choose the best combination of components to achieve your desired performance goals.

How To Update SBC Heads – Tips And Tricks

How To Update SBC Heads


Choosing the right cylinder heads for your small block Chevy (SBC) engine ensures optimal performance. With so many options available, it can be overwhelming to know where to begin. Here are some tips and tricks guide on how to update SBC heads.

If you’re looking to update your Small Block Chevy (SBC) heads, you should keep a few tips and tricks in mind.

  1. Choosing the right heads for your engine is important. When selecting heads, you’ll want to consider factors like your engine’s compression ratio and the camshaft you’re using. Once you’ve chosen the right heads, it’s time to install them. Be sure to follow the manufacturer’s instructions carefully and torque the bolts to the proper specifications.
  2. It’s also a good idea to check the pushrod length and adjust it if necessary. To tuning your new heads, you’ll want to pay attention to the air/fuel ratio and make any necessary adjustments to optimize performance. Additionally, you may need to adjust your ignition timing to get the most out of your new heads.
  3. Don’t forget to break in your new heads properly. This means running the engine at varying RPMs for a few minutes and then changing the oil.

 Performance Vs Budget Upgrades

To upgrading your computer, you may face the dilemma of choosing between performance and budget upgrades. Performance upgrades are those that will enhance the speed and functionality of your computer, while budget upgrades are those that are more affordable but may not yield the same level of improvement.

For instance, installing a new graphics card or increasing the amount of RAM can significantly boost your computer’s performance, but these upgrades can come with a hefty price tag.

On the other hand, upgrading to a larger hard drive or installing a more efficient cooling system can fall under the category of budget upgrades as they don’t require as much investment but can still make a noticeable difference in your computer’s operation.

It’s important to strike a balance between performance and budget upgrades depending on your specific needs and budget constraints. If you use your computer for intensive tasks such as gaming or video editing, investing in high-performance upgrades may be worth it.

 Choosing The Right SBC Heads For Your Engine

To building a high-performance engine, choosing the right cylinder heads is crucial. Many options are available for small-block Chevy engines (SBC), making the decision-making process even more daunting. However, understanding your engine’s specific requirements and intended use allows you to narrow your options and find the perfect heads for your application.

One of the most important factors to consider is the size of your engine and its compression ratio. Heads with larger intake and exhaust runners are best suited for larger displacement engines, while smaller runners are better for smaller engines. Similarly, higher compression ratios require heads with smaller combustion chambers to prevent detonation.

Another important consideration is your engine’s intended use. If you plan on using it for drag racing or other high-revving applications, heads with larger valves and higher airflow capacity will provide the necessary performance gains. On the other hand, if you’re building a street machine, heads with a smaller intake runner and more low-end torque may be more.

 Installation Process Of Upgraded SBC Heads
