About Our Cylinder Heads

Cylinder heads are one of the most critical components in an engine, controlling airflow into and out of the combustion chamber. By managing the intake and exhaust flow, cylinder heads play a major role in determining engine performance, efficiency, and power output. High-performance cylinder heads are designed with improved port shapes, larger valves, and optimized combustion chambers to maximize airflow and combustion efficiency.

Upgrading cylinder heads is one of the most effective ways to increase horsepower and torque. Performance heads improve air and fuel flow into the engine while allowing exhaust gases to exit more efficiently, resulting in better combustion and increased power. 

Cylinder heads are available in both aluminum and cast iron designs. Aluminum heads are lighter and dissipate heat more efficiently, making them a popular choice for performance applications, while cast iron heads are known for durability and cost-effective replacements.

Common applications include small block and big block V8 engines, as well as modern LS and LT platforms. Whether you're building a high-performance engine or upgrading a factory setup, choosing the right cylinder heads is essential for maximizing airflow, improving efficiency, and achieving reliable horsepower gains.

Cylinder Heads FAQs

What is the purpose of a cylinder head?

The cylinder head forms the top portion of the combustion chamber. It seals the cylinders, houses valves and ports, supports combustion, and facilitates cooling and airflow.

How do I choose the right cylinder heads for my engine?

Match by engine family, port type (rectangular, cathedral, etc.), valve layout (2-valve, 4-valve, etc.), and intended use (street, racing, forced induction). Ensure compatibility with your block, camshaft, intake manifold, and valvetrain.

Can I reuse the head gasket or old parts when updating cylinder heads?

It’s highly recommended to always use new head gaskets and proper fasteners when installing a new or remanufactured head. Reusing old components can compromise sealing, performance, and reliability.

What are signs that a cylinder head is damaged or failing?

Common symptoms include:

• Overheating
• Misfires or poor compression
• Coolant in oil or oil in coolant
• White exhaust smoke
• Leaking or cracked head
• Loss of power or rough running

How important is proper head bolt torque?

Very important. Correct torque ensures the head is clamped evenly and the head gasket seals properly under combustion pressure. Improper torque can lead to warping, leaks, or gasket failure.

Do TSP cylinder heads come with a warranty?

Yes — all TSP cylinder heads include a 1-year limited warranty against manufacturing defects. For more details, visit our Warranty & Returns page.
