- Gasket set
- New valve springs
- Performance valves
- Installation instructions
Tools and Materials Required
Before starting the installation, gather the necessary tools and materials. Having everything on hand will make the process smoother and more efficient.
- Socket set
- Wrench set
- Torque wrench
- Drill and drill bits
- Bench grinder
- Safety goggles and gloves
Step-by-Step Installation Process
Step 1: Preparation
Begin by removing the cylinder heads from the engine block. Make sure the engine is cool and disconnect the battery. Drain any fluids and remove the intake manifold if necessary. Label all components to simplify reassembly.
Step 2: Cleaning the Heads
Thoroughly clean the cylinder heads to remove any oil, dirt, or debris. Use a degreaser and a wire brush to ensure all surfaces are clean. This step is crucial for achieving a proper seal when reassembling the heads.
Step 3: Porting the Heads
Using the tools provided in the Darton head porting kit, start the porting process. Carefully remove material from the intake and exhaust ports to enhance airflow. Follow the instructions provided with the kit to ensure you achieve the desired shape and size.
Step 4: Installing New Valves and Springs
Once the porting is complete, install the new performance valves and valve springs. Ensure that the springs are seated correctly and that the valves operate smoothly. This step is critical for maintaining engine performance.
Step 5: Reassembly
Reassemble the cylinder heads by following the reverse order of disassembly. Use a new gasket set to ensure a proper seal. Torque the bolts to the manufacturer’s specifications, ensuring even pressure across the head.
Step 6: Final Checks
Before starting the engine, double-check all connections and ensure that there are no loose parts. Refill any fluids that were drained during the process. Once everything is in place, reconnect the battery and prepare for the first start.
Testing and Tuning
After installation, it is essential to test and tune the engine for optimal performance. Monitor engine parameters and make adjustments as necessary. Consider using a dynamometer to measure horsepower and torque gains accurately.
Conclusion
Installing Darton head porting kits on small-block Chevys can significantly enhance engine performance. By following this step-by-step guide, you can ensure a successful installation and enjoy the benefits of improved airflow, horsepower, and torque. Always remember to prioritize safety and take your time during the installation process for the best results.
