Why Choose a David Vizard Porting Kit?

David Vizard's Porting Kit offers several performance and efficiency benefits, especially for engine builders and performance shops focused on cylinder head porting.

Precision and Consistency

The kit includes high-quality carbide rotary files, straight cartridge rolls, and flap wheels designed for fine, controlled shaping of intake and exhaust passages. This precision helps achieve consistent port shapes, which is critical for optimal airflow and predictable performance results.

Versatility for Multiple Head Types

The tools are suitable for both cast-iron and aluminum cylinder heads, allowing the shop to work on a wide range of applications without needing multiple specialized kits.

Support for Advanced Porting Techniques

David Vizard’s expertise covers everything from basic porting to advanced methods like pocket porting, unshrouding valves, and optimizing intake runners. The kit’s components enable shop technicians to perform these techniques with the right grits and shapes, maximizing flow velocity and power potential. 

Compatibility with Flow Testing

The kit supports the principles and procedures in How to Port & Flow Test Cylinder Heads, which emphasizes using a flow bench to verify results. This ensures that porting work is not just shaped for looks but is validated for actual airflow gains.

Time and Skill Efficiency

By having a complete, well-organized set of tools, the shop can reduce setup time, minimize tool changes, and maintain a professional workflow. This is especially valuable in a busy shop where efficiency directly impacts throughput and customer satisfaction.

Professional Image and Customer Confidence

Using a recognized, high-quality porting kit from a respected figure like David Vizard signals to customers that the shop uses proven, performance-oriented methods. This builds trust and can justify higher service or performance packages.

Educational Value

The kit can be paired with Vizard’s instructional materials, allowing the shop to train staff in best practices, reduce mistakes, and maintain high standards across all porting jobs.

In Summary:

A David Vizard Porting Kit enhances an auto shop’s ability to deliver high-performance, consistent, and customer-verified cylinder head porting. It’s a worthwhile investment for shops that want to maximize airflow, improve engine output, and maintain a reputation for precision and expertise.

Measuring Combustion Chamber Volume

The volume of a cylinder head's combustion chamber is an incredibly important spec. Too big, and you are leaving compression on the table. Too small, and you might hurt the engine. Measuring it isn't hard, but you need to follow the right steps in order to get an accurate result.

Goodson teamed up with EngineLabs.com to create this tech article and video.
