David Vizard's How to Port & Flow Test Cylinder Heads (S-A Design)

Great book to learn how to get high performance out of your heads ..love the book. Great tips

This book will help you understand how your engine breaths and how to get more out of a set of cylinder heads.

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.

this is a good book despite the self indulgence of the author his text and drawing content is very good and enlightening to a person with a bent towards the subject matter he definatly imparts a good deal of quality info however he is enamoured with graphs, they explain everthing!! if you have a degree in quantum physics. some are self explanatory but the bulk of them there is no explanation that make sense of them to me the left school in the eight grader I am by no means smart or stupid just a small note in how to interpret each graph would have made this a superb book and I am still glad I paid for it and had it sent to Australia would be head porter from down under

As advertised. Quick shipping. Would purchase again from this vendor again

This has increased my understanding of the internal combustion process greatly. I recommend it especially if you are thinking a a camshaft upgrade.

Have a bunch of Davids books, and have ported SB chevy heads using his methods with good results.

Some say too technical. Not so for me. I like knowing why when learning a new skill. Keeps me from undervaluing the practical applications of the skill. Well worth the read. If you get it I would start with chapter 7 and read the 5 golden rules then start at the beginning. Now you’ll be ready to take notes.

Super

The author takes into account only the "classic" heads 2 valve per cylinder engines Americans, for hemispherical heads is wasted on a page and to the heads with 16 valves even less. If you want to take action on a European or Japanese modern engine it is completely useless. It would have been nice to know this in the sales description of the book and then decide whether to buy it or not. L'autore prende in consisderazione solo le teste "classiche" a 2 valvole per cilindro dei motori Americani, per le teste emisferiche si spreca in una pagina e per le teste a 16 valvole anche meno. Se si vuole intervenire su un motore moderno Europeo o Giapponese è completamente inutile. Sarebbe stato bello sapere ciò nella descrizione di vendita del libro per poi decidere se acquistarlo o meno.

Es muy facil de leer lleno de ejemplos, e historias y te da el enfoque para entender la preparacion de culatas

As usual with the Mr Vizard's books, it's a very well done work. The quality of the explanations, pictures and drawings is perfect. Nevertheless, first of all, intended to traditionnal american iron. Few informations about hemi and four valve heads.

I've seen all kinds of media and books on Porting cylinder heads, both for racing and for more efficient fuel mileage. His book is much better, for amateurs and even more for professionals. Outstandingly clear, excellent graphics and charts and explanations! Well written, technically simple language. Can't recommend it enough.
