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.
