Buying Guide

Even though you might know many brands for head replacement, choosing the best aluminum heads for small block Chevy is still confusing.

As you have seen above, each product has pros and cons. There is no single product without any cons. However, it is a matter of priorities. According to your needs, you might choose the best product for you.

So, to make it easier, here is a small guide you can always refer to when choosing the best aluminum heads for small block Chevy.


Like most other car aftermarket pieces, the material is very important or not the most important thing when choosing the product.

Generally, cylinder head replacements are either iron or aluminum. Iron is a very durable and heavy-duty metal but it is heavier than aluminum, so, more difficult to install.

Further, aluminum withstands heat better than iron. So, the combustion chamber volume of aluminum heads is higher than that of iron. This results in overall better engine performance.

Also, iron is cheaper than aluminum, however, aluminum is certainly better. So, in a nutshell, if you want to save more money but still get something that works, iron is a good option. On the other side, if you want the best of the best, then choose aluminum head replacements.

Aluminum models, on the other hand, are more easily accessible, buy, and find. Mainly, the overall budget affects this choice.

Combustion Chamber

This is usually a number followed by the abbreviation cc in most head replacements. This abbreviation stands for cubic centimeters which is basically a volume.

Also, this measures the combustion chamber of the head replacement which indicates a lot about its performance.

Of course, large ports are better and have higher gas intake volume. However, small ports are designed today to give the same exact performance without having to use very large ports.

Note that if you go with small ports, you might notice a slight decrease in the RPM. So, here, you need to balance your priorities.

Which Chevy cars are using and for what purposes. Choosing the right port volume intake will lead to increased torque and better throttle response.

Port configuration intake

Port intake will connect with the intake manifold, so, they must have the same shape. Some intakes have a rectangular shape while others are round or oval-shaped.

Hence, you need to double-check the manifold intake, so, both match together.

Another important aspect here is the intake port location. This should be also checked for the exhaust port.

Ideally, you should get something that matches the original. However, a slightly raised intake port is not a major problem. Instead, it might give better flow and thus, better engine performance.


CNC is short for computer numerical control which means the aluminum metal of the head is cast.

Metal casting is very important for metals in the head to get it exactly the same shape and size as the factory one. So, intakes can fit easily into the head.

Whereas CFM is short for cubic feet of air per minute. This is the amount of airflow passing through the engine.

It has to do with the overall performance of the engine. This number is usually written on the head itself, so, when replacing this head, you need to consider getting the same number or above.


If you choose an aluminum head made for small-block Chevy, there is no problem. These will typically fit but if you choose a universal head, you should make sure its dimensions are suitable for the small block engine of your Chevy.

Apart from the size of the head, the size of valves is also important. The largest the better, however, large valves are sometimes incompatible with your engine.

Hence, getting heads that keep the original dimensions is better. If you decided to get one with larger valves, just ensure everything fits in.

Coil bind

Coil bind is the maximum valve lift of any head you are getting. Coil bind is measured in inches and should be set to a suitable number to avoid hitting the engine.

This factor, although mostly you will get it right, is also related to the engine performance.


What makes the best aluminum head?

The above guide has numerous points to consider when replacing the head.

Generally, what makes the aluminum head better than others are the capacity of combustion, the intake valve dimensions, and the runner intake volume for more airflow.

These points, if satisfied in your head, make sure you will have the best working aftermarket piece.

What happens if the cylinder head is damaged?

The head is a very important piece in the small block Chevy. It closes the combustion chamber allowing for air and gas to combust under suitable pressure and combustion capacity.

If the head is damaged or stopped functioning for any reason, there won’t be proper combustion.

This may lead to engine misfiring or it stops working at all.

Should I replace the cylinder head once damaged?

Although you can still drive your vehicle with a damaged cylinder head, this is not recommended at all.

A damaged cylinder head will cause problems with the combustion process which at the end may cause failure to the whole motor.

Can I install the head replacement myself?

If you are not experienced in car aftermarket pieces then we don’t recommend you do this.

The installation process might seem easy but in the end, it needs a mechanic to get the job done perfectly.

Typically, installing should take a few hours if everything else is ok. Also, if the cylinder head is only cracked not totally damaged, the mechanic can fix it by using TIG welding.

What causes the cylinder head to damage?

Sometimes the reason is that it is just the lifespan of the product. It had worked enough years, so, it is worn out and needs replacement.

Other times it is a manufacturing defect. Many heads are made of a mixture of metals like iron and aluminum. Each of these metals reacts differently to heat.

So, they expand differently when heated and this results in head cracking which eventually leads to its damage if not solved.

Also, excess heat may be another reason for head damage even though they are made to resist heat but to certain limits.


Heads are very important parts in the overall engine compartment that you might not have thought of before.

Sometimes, it is the only reason your vehicle is not performing as required is because of the head.

So, part of maintaining your car is to check the cylinder head. With so many options in the market, the choices became difficult.

However, this review and buying guide will help you a lot in determining the best product and reaching a decision about the best aluminum heads for small block Chevy.
