Buying Guide
`
`
Choosing the right aluminum heads for your 454 can be tricky. Here are some factors to consider.
`
`
- `
- Engine Use: Are you building a street car or a race car? Street cars need heads that offer good low-end torque. Race cars need heads that maximize high-end horsepower.
- Engine Displacement: Larger displacement engines need heads with larger runners. Smaller engines need smaller runners. This helps maintain velocity and efficiency.
- Valve Size: Larger valves allow for more airflow. But they may require additional machining. Make sure the valve size is compatible with your engine.
- Combustion Chamber Size: Choose a combustion chamber size that matches your desired compression ratio. Higher compression ratios increase power. But they may require higher octane fuel.
- Budget: Aluminum heads range in price. Set a budget before you start shopping. Don’t forget to factor in the cost of installation.
- Intake Manifold Compatibility: Ensure the heads are compatible with your intake manifold. Mismatched parts can hurt performance.
- Valve Springs: Select valve springs that match your camshaft. The correct spring pressure is crucial for performance and reliability.
- Professional Installation: Unless you’re experienced, consider professional installation. Improper installation can damage your engine.
