Buying Guide: What To Consider When Choosing Heads For 351W?
Cylinder heads are available in various designs and specifications; So, choosing the right cylinder head is not an easy task. To make the right choice, you need to consider many different factors, these include:
Most cylinder heads are made of either iron or aluminum. The iron head is a good choice for those on a mid-range budget due to its lower price. Meanwhile, aluminum models are easier to find, buy, and use.
In addition, to better understand the difference between the iron cylinder head and the aluminum cylinder head, watch this video.
2. Intake Port Volume
When you check the specifications of heads, you may notice the word `cc` appearing in the description. The word “cc” stands for cubic centimeters and is commonly used for port flow, combustion chamber, and total volume. For intake port volume, it indicates the overall volume of the port.
When it comes to intake port volume, many people assume that “bigger is better.” To be honest, this is a common mistake. Small ports can compete with larger ports in terms of flow, air, and power. Usually, small blocks of street engines are packaged with a small intake port for higher inlet velocity.
3. Intake Port Configurations
It is one of the factors that make the cylinder heads differently. Intake port configurations can be oval, circular, rectangular, and more. Therefore, when buying a cylinder head, you need to make sure it fits the intake manifold.
3. Valve Angle
When looking at the parameters of the cylinder heads, you may come across the term “valve angle.” Simply put, it indicates the angle of the valve towards the block deck.
In fact, the valve angle dramatically affects the airflow of the cylinder head. Therefore, by choosing the right valve angle, you can significantly improve the engine’s performance.
4. Valve Size
Vehicle owners can get better flow and performance with large valves. However, they often forget that small block heads usually do not fit huge valves.
Many aftermarket versions focused on original factory chamber valves. Meanwhile, some other products make room to get the benefits of large valves.
5. CNC Porting
In some heads, you may come across the term “CNC” (Computer Numerical Control). It is used for the heads that have been cast in a machined way. Technically, liquid aluminum and other metal were used to cast the cylinder head.
Manufacturers often use the CNC manufacturing process to create many heads, although it can be less precise.
However, thanks to this process, users can get the exact size and shape of the combustion chamber and intake runner, which can improve the flow.
