Any professional performance engine builder will likely tell you the most powerful and important component in an engine are cylinder heads. If you can afford to invest serious money in one component for a street engine, in most cases it should be a set of cylinder heads. While the small-block Chevy engine has been well-chronicled, specific in-depth information on this important component has been more elusive. This book shows you how to choose the best cylinder head for your application. It covers both Gen I and Gen II small-block Chevy versions, occasionally touching on the Gen III and Gen IV production versions. This book taps into some of the best small-block Chevy cylinder head resources this country has to offer with a combination of insight and best estimates, because much of what we know about port design and airflow management falls under the category of art rather than science.
High-Performance Chevy Small-Block Cylinder Heads is designed exactly like its predecessor, High-Performance Chevy Small-Block Cams & Valvetrains, in that it starts with the basics and works into more in-depth concepts and variables in an attempt to uncover all those subtle nuances that make up the small-block Chevy. It features airflow basics, extensive flow bench tests (using the Superflow 600 bench), information on production and aftermarket heads, rebuilding and assembly, and basic porting techniques.
