FAQs about Cylinder Head

What is a cylinder head and why is it important?

A cylinder head sits on top of the engine block, sealing the combustion chamber and housing critical components like valves, spark plugs, and ports. High-quality engine heads improve airflow, combustion efficiency, and overall engine performance.


The cost to replace a cylinder head varies depending on the engine type and head material. For standard engines, high-quality SBC heads, BBC heads, or LS heads from EVIL ENERGY range from $300 to $750, making them an affordable option for both daily drivers and performance builds. Labor costs for installation may vary, but the heads themselves provide excellent value without compromising performance.

LS heads are designed for GM LS series engines and offer modern port designs for better airflow and higher RPM performance. In contrast, SBC heads are for small-block Chevy engines, and BBC heads are for big-block Chevy engines, each tailored to specific block dimensions and performance needs.


Signs of a bad engine head include overheating, white smoke from the exhaust, loss of power, coolant leaks, or oil contamination. Using quality SBC heads, BBC heads, or LS heads from EVIL ENERGY can help prevent common issues and improve engine reliability.

Yes, some cylinder heads can be repaired, depending on the type of damage. Minor warping, cracks, or valve seat wear can often be fixed through head machining or resurfacing. However, for high-performance builds, replacing with a new LS head, SBC head, or BBC head from EVIL ENERGY is often more cost-effective and ensures optimal performance.
