Things to Consider Before Choosing the Best SBC Heads for 500 HP

Check these things before choosing the Best SBC Heads for 500 HP:

Things to Consider Before Choosing the Best SBC Heads for 500 HP

1. Intake Ports:

The “bigger is not always better” ideology perfectly defines the intake ports of SBC cylinder heads.

Larger ports give greater flow at higher RPMs and would probably cause the torque numbers to fall off.

On the other hand, smaller intake port volumes deliver a crisper throttle response with low-end torque and usually produce satisfactory results for street performance and part-time race vehicles.

While larger intake volumes can be beneficial to larger displacement engines, intake parts with the smallest volume and highest efficiency are preferable.

2. The Exhaust

Good flowing exhausts enable your 500 HP engines to receive good power.

In this case, a cylinder head with slightly lower-flowing intake ports and high-flowing exhaust parts with a small cross-sectional area is recommended for your SBC 500 HP engines.

3. The Combustion Chamber

The shape, size, and design of the combustion chamber is a crucial factor affecting the engine’s performance.

Before purchasing an SBC head for your 500HP engine, ensure that you determine the best combustion chamber for the engine based on its specifications.

4. The Valves

Just like in the case of the intake ports, bigger caves are not always the best choice for some engines.

Determining the right valve for your 500 HP SBC engine is a worthy factor to consider because it affects the overall output of the engine.

5. Compatibility of The Engine Head

The result of using an incompatible cylinder head for your SBC engine is pretty obvious. It won’t fit! It won’t work!

That’s why you need to check the specifications of your SBC engine and the engine head you are about to purchase to ensure that they are compatible with each other.

Conclusion
