Header Installation Guide: Step-by-step for Edelbrock and Hooker Headers

by

Installing headers can significantly improve your engine’s performance. This guide will walk you through the step-by-step process for installing Edelbrock and Hooker headers.

Tools and Materials Needed

  • Header kit (Edelbrock or Hooker)
  • Socket set
  • Wrenches
  • Torque wrench
  • Gasket scraper
  • New gaskets
  • Anti-seize compound
  • Safety goggles
  • Gloves

Preparation Steps

Before starting the installation, it’s essential to prepare your workspace and vehicle. Follow these steps:

  • Ensure the vehicle is parked on a level surface.
  • Disconnect the battery to prevent electrical issues.
  • Raise the vehicle using jack stands for better access.
  • Remove any components obstructing header access, such as the exhaust system or engine covers.

Removing Old Headers

If you are replacing old headers, follow these steps:

  • Remove the old headers by unscrewing the bolts with a socket wrench.
  • Carefully detach the exhaust pipes connected to the headers.
  • Remove any remaining gaskets or debris from the cylinder head.

Installing New Headers

Now that the old headers are removed, you can install the new Edelbrock or Hooker headers:

  • Place the new header into position over the cylinder head.
  • Align the header with the bolt holes and insert bolts loosely.
  • Repeat the process for the other side if applicable.
  • Once both headers are in place, tighten the bolts in a crisscross pattern to ensure even pressure.

Torque Specifications

Refer to the manufacturer’s specifications for the correct torque settings. Typically, the torque range is:

  • Header bolts: 20-25 ft-lbs
  • Collector bolts: 30-35 ft-lbs

Reconnecting Exhaust System

After securing the headers, reconnect the exhaust system:

  • Attach the exhaust pipes back to the headers.
  • Ensure all clamps and bolts are tightened securely.
  • Check for any leaks before proceeding.

Final Checks

Before finishing up, perform these final checks:

  • Double-check all bolt tightness.
  • Inspect the area for any tools left behind.
  • Reconnect the battery.
  • Start the engine and listen for any unusual noises.

Conclusion

Installing Edelbrock or Hooker headers can enhance your vehicle’s performance and sound. Follow these steps carefully for a successful installation.
