Porting Heads is an art and science.
All of these changes combine to produce optimal Flow velocity through the engine for maximum power..
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.
The book covers blending the bowls, a basic porting procedure, and also covers pocket porting, porting the intake runners, and many advanced procedures.
Vizard shows how to optimize Flow paths through the heads, past the valves, and into the combustion chamber.
You are also shown how to build a high-quality Flow bench at home so you can Test your work and obtain professional results.
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.
Vizard goes into great depth and detail on porting aftermarket heads.
All the aspects of porting stock as well as aftermarket Heads in aluminum and cast-iron constructions are covered.
Few other engine builders have the same level of knowledge and skill porting engine Heads as David Vizard.
Porting demands the right tools, skills, and application of knowledge.
It takes a craftsman\'s touch to shape the surfaces of the head for the optimal Flow characteristics and the best performance.
