Disassembly and Inspection
Before you start the rebuild process, you need to disassemble the cylinder head and inspect it for damage. Here are the step-by-step instructions for disassembling the cylinder head:
- Remove the cylinder head from the engine block.
- Remove the intake and exhaust manifolds.
- Remove the valve cover.
- Remove the valves, springs, and keepers.
- Remove the piston rings and connecting rods.
- Inspect the cylinder head for damage, such as cracks, warping, or worn-out parts.
Tips for inspecting the cylinder head for damage:
- Look for cracks or warping on the cylinder head surface.
- Check the valve seats for wear or damage.
- Inspect the valve guides for wear or damage.
- Check the cylinder head bolts for damage or wear.
Cleaning and Preparation
After disassembling the cylinder head, you need to clean it thoroughly to remove any debris or buildup. Here are the instructions for cleaning the cylinder head and its components:
- Use a parts washer to remove any debris or buildup from the cylinder head surface.
- Use a wire brush to remove any rust or corrosion from the cylinder head surface.
- Use a gasket scraper to remove any old gasket material from the cylinder head surface.
- Inspect the valve seats, guides, and other critical areas for damage or wear.
Tips for preparing the cylinder head for reassembly:
- Check the valve seats for wear or damage.
- Inspect the valve guides for wear or damage.
- Check the cylinder head surface for flatness.
Valve and Seat Preparation
To ensure a proper valve-to-seat seal and optimal valve clearance, you need to prepare the valves and seats for reassembly. Here are the instructions for preparing the valves and seats:
- Grind the valves to the correct size and shape.
- Lap the valves to ensure a proper valve-to-seat seal.
- Install the valve stem seals.
Tips for ensuring a proper valve-to-seat seal and optimal valve clearance:
- Use a valve grinding tool to grind the valves to the correct size and shape.
- Use a valve lapping tool to lap the valves to ensure a proper valve-to-seat seal.
- Check the valve clearance with a feeler gauge.
Reassembly and Installation
After preparing the cylinder head, you can start the reassembly process. Here are the step-by-step instructions for reassembling the cylinder head:
- Install the valves, springs, and keepers.
- Install the piston rings and connecting rods.

FAQs
1. What is the difference between a 22RE and 22REH cylinder head?
The main difference between a 22RE and 22REH cylinder head is the material used in their construction. The 22RE cylinder head is made of cast iron, while the 22REH cylinder head is made of aluminum. The aluminum head is lighter and has better heat dissipation properties, which can improve engine performance and durability. However, the aluminum head is also more expensive than the cast iron head.
2. How many valves does a 22RE cylinder head have?
The 22RE cylinder head has four valves per cylinder, which is a common design for many modern engines. This configuration allows for better airflow and fuel efficiency, which can improve engine performance and fuel economy.
3. Can I use a 22RE cylinder head on a 22R engine?
No, a 22RE cylinder head is not compatible with a 22R engine. The 22RE engine has a different cylinder bore and stroke than the 22R engine, which means that the cylinder head and other engine components are not interchangeable.
4. How much horsepower can I expect from a 22RE cylinder head?
The horsepower that can be expected from a 22RE cylinder head depends on various factors, such as the engine’s compression ratio, camshaft design, and fuel injection system. However, with the right modifications, a 22RE engine can produce up to 200 horsepower or more.
5. What are the benefits of porting and polishing a 22RE cylinder head?
Porting and polishing a 22RE cylinder head can improve engine performance by increasing the flow of air and fuel into the engine. This process involves enlarging the intake and exhaust ports, smoothing the surfaces, and reshaping the combustion chambers. The result is a more efficient engine that produces more horsepower and torque.
