It could be quite a challenge when choosing car parts that will be most suitable for your vehicle and what will be beneficial for your engine.

Choosing the right metal part and size with correct dimensions can be tricky as different vehicles have different mechanisms. Large vehicles such as trucks and tractors have a completely different arrangement of interior mechanical parts.

On the other side vehicles such as cars race cars requires different parts for them to function. Aluminum heads are the most common and highly efficient to improve your car engine capability out of all the mechanic parts.

Here I have listed the best aluminum heads for small block Chevy that will surely improve your car performance.

It also increases your engine’s horsepower up to 20-30%, which in turn causes your engine to reduce output power wastages in the form of heat or combustion.

In addition to that, this mechanic part also secures safety to your overall car as it prevents oil leakage and causes your vehicle to accelerate without negatively affecting the mileage. Furthermore, this part is extremely quick and easy to install, and once you are done, you will quickly notice an improvement in the header and power steering pump.

The overall aluminum cylinder head has no imperfections such as corrosion, bumps, etc., adding to its perfection for your car. As you may know, aluminum does not rust when it is in contact with water/moisture, which means that this part can work for a long time before requiring any replacement or maintenance.

If you are wondering about the drilling process, you do not have much to worry about as it can be easily drilled due to the already present holes in the cylinder. This auto part even works if the base of your engine is old or requires replacement as it can hold the immense pressure exerted without cracking due to its low malleability and ductility.

Although the auto part works universally on all vehicles, one drawback is that it is quite expensive to purchase. Some buyers might argue about the price being high since the part itself is quite small and compact.
  • No chances of leaking
  • Universally fit
  • Increases horsepower
  • It can be quickly drilled
  • High price range

How Do I Install Heads On Small Block Chevy?

Before start installing, there are a couple of things required to do, such as clean your head and gasket from all the dust and oils with a cotton cloth instead of paper. After cleaning, it is time you place your gasket carefully to its accurate position. Lastly, install the heads on very carefully and take your time; then, you can finally torque and seal them tightly.

Are Aluminum Heads Better Than Iron Casts?

To keep in mind, though, both kinds can damage the engine if it overheats. However, aluminum is easier to install and replace as aluminum heads are light-weighted than iron casts.

But when it comes to providing power, aluminum heads can preserve heat more than iron casts and provide more power to the engine as it has more thermal conductivity than iron casts, so it can dissipate more heat.

Does The Combustion Chamber Size Affect The Compression Ratio?

Yes, it does! The smaller combustion chamber will give you a higher compression ratio, but it can create clearance problems with pistons and valves. And a large combustion chamber will reduce the compression ratio, which will result in cooler burning temperatures, eventually leading to inefficient combustion.

Which SBC Head Is Best, And How Do I Choose?

This depends on your preference, but I believe that if you are choosing a head, mainly look for the one with the best combustion chamber, intake valves, great durability, high-performance rate, exhaust valves, as well as focus on the one that would not cause your engine to fail.

Moreover, one of the best ways to test the heads is to lock them and to make dyno pulls. This will enable you to see which one has the extreme power but not choose the one with the highest power. It will also allow you to see a confined rpm, which would not be a good choice for you. When choosing a head through this test, it is best to see inclusive energy and torque results.


Choosing the best aluminum heads for small block Chevy can be difficult work as they might have a lot of things in common and make it hard to choose the best one.

However, I would recommend the Flotek Aluminum Cylinder Head as it is one of the top brands with the best aluminum heads and guarantees to increase your engine’s horsepower. As a result, make your engine run smoothly.

It is important to choose the right aluminum heads, so it does not cause your engine any harm or worsen your car parts. It is also necessary that you do your research before making an investment into something that will have a big impact on your vehicle; I have listed down these for you so you can make the best choice according to your preference and budget.
