Covering everything from basic techniques to advanced procedures, this book empowers readers to optimize airflow through both stock and aftermarket aluminum and cast-iron heads. It includes expert insights on building a DIY flow bench for precise testing, making it an essential resource for maximizing engine power and efficiency. ## Description Porting heads is an art and science. It takes a craftsman's touch to shape the surfaces of the head for the optimal flow characteristics and the best performance. Porting demands the right tools, skills, and application of knowledge. Few other engine builders have the same level of knowledge and skill porting engine heads as David Vizard. All the aspects of porting stock as well as aftermarket heads in aluminum and cast-iron constructions are covered. Vizard goes into great depth and detail on porting aftermarket heads. Starting with the basic techniques up to more advanced techniques, you are shown how to port iron and aluminum heads as well as benefits of hand and CNC porting. You are also shown how to build a high-quality flow bench at home so you can test your work and obtain professional results. Vizard shows how to optimize flow paths through the heads, past the valves, and into the combustion chamber. The book covers blending the bowls, a basic porting procedure, and also covers pocket porting, porting the intake runners, and many advanced procedures. These advanced procedures include unshrouding valves, porting a shortside turn from the floor of the port down toward the valve seat, and developing the ideal port area and angle. All of these changes combine to produce optimal flow velocity through the engine for maximum power.

Great tips ### ⭐⭐⭐⭐⭐ Very helpful for a DIYer *by A***R on September 29, 2025* This book will help you understand how your engine breaths and how to get more out of a set of cylinder heads. ### ⭐⭐⭐⭐⭐ Great Vizard book, may be too advanced/technical for casual performance buffs *by K***Z on January 7, 2014* If you have ever thought about porting your own heads or done a few, this book will be extremely helpful and interesting. As usual, David explains and shows actual technique to an extent you would have to search years to find otherwise, in my opinion. I ported my first set of heads in college and they probably were OK, but this book would have helped them reach their full potential! I think many people can also just benefit from understanding what makes for good flow when they are looking at various possibilities for their projects. I also liked all the information about building your own flow bench, and wished I had the time and space to do that in the near future. ## Frequently Bought Together - How to Port & Flow Test Cylinder Heads (S-A Design) - David Vizard's How to Build Horsepower: Proven Methods for Increasing Horsepower in Any Engine (S-A Design) - How to Build Horsepower, Volume 2: Carburetors and Intake Manifolds --- ## Why Shop on Desertcart? - πŸ›’ **Trusted by 1.3+ Million Shoppers** β€” Serving international shoppers since 2016 - 🌍 **Shop Globally** β€” Access 737+ million products across 21 categories - πŸ’° **No Hidden Fees** β€” All customs, duties, and taxes included in the price - πŸ”„ **15-Day Free Returns** β€” Hassle-free returns (30 days for PRO members) - πŸ”’ **Secure Payments** β€” Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** β€” Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.co.za/products/1874696-david-vizards-how-to-port-and-flow-test-cylinder-heads](https://www.desertcart.co.za/products/1874696-david-vizards-how-to-port-and-flow-test-cylinder-heads) --- *Product available on Desertcart South Africa* *Store origin: ZA* *Last updated: 2026-07-25*
