Buying Guide

When it comes to buying a good quality set of aluminum cylinder heads for a small block Chevy, there are certain things you need to take into consideration. These include:

The Build

There are a lot of reasons why so many people prefer aluminum cylinder heads over cast iron ones; one of these is that these heads are much lighter than their iron counterparts. And because of this, your car is able to go faster as it has to carry less weight now. And so, if an increase in speed is one of the reasons why you are getting aluminum heads, you need to make sure that the one that you are buying is towards the lighter side.

Furthermore, while Aluminum is a strong metal, it is not as tough as cast iron which is why you need to make sure that the cylinder heads are made up of strong aircraft-grade aluminum for ultimate durability. Also, if you plan to use your car frequently, then it is also preferred that your aluminum heads have hardened seats to make them more temperature resistant and increase their durability.

Combustion Chamber Capacity

Another important feature of cylinder heads that you need to take into consideration is the capacity of the combustion chamber. This is because it is the major factor that determines the compression in an engine. And the higher the compression is in an engine, the more efficient it will be, as due to high compression, more energy can be harvested from combustion. And so this makes an engine more fuel-efficient.

Therefore, when it comes to combustion chambers in cylinder heads, the ones with smaller capacities are preferred over larger capacities. This is because the smaller the volume inside the chamber will result in an increased compression in the engine. But this can also result in an increase in temperature, which can be damaging to the heads. This is why it is important to get one that has the perfect balance between the two.

Compatibility

Perhaps one of the most obvious things to consider when getting aluminum cylinder heads for a small block Chevy is to make sure that the ones you are getting are compatible with your car. This is because if you get a set of aluminum cylinder heads that are not compatible with your vehicle, then they will not fit properly, which will result in your money going down the drain. And so, it is important to double-check the vehicles that a set of cylinder heads is compatible with before confirming your purchase.

Air Flow

Another important factor to consider when buying a set of aluminum cylinder heads for your vehicle is the amount of air that it allows to pass through. Larger airflow increases the efficiency of a car. This is why if you are looking for a set of cylinder heads that increase efficiency, you need to get one that has large valves that have a 2.02-inch intake and 1.6-inch exhaust combination. This will allow ample air to pass through and increase the efficiency of your engine.

Price

There are a lot of aluminum heads available in the market, all of varying quality. And while it can be tempting to get a cheaper option to save money, if it is not a good quality one, it can do more harm than good. This is because these heads can have off-centered holes that would require further drilling from your side in order to have them fit during the installation process. They can also give you a bad performance or simply just not work properly.

All this can not only waste your money but bring you back to square one and in need of a better quality set of heads. This is why it is important to invest in some good quality and slightly expensive heads from the start. This is because that investment would be worthwhile as you will be not only getting well-performing heads but also ones that are sure to last you a long time. Although low-cost heads are not always bad quality, and if you buy ones from a trusted brand, then you are probably going to get decent ones.
