Edelbrock SB-Chevy Performer RPM E-TEC Aluminum Cylinder Heads

Product images may differ from actual product appearance.

Engineered to greatly increase performance and efficiency, E-TEC heads fit SB-Chevy 302-400ci engines with ''Vortec'' style intake manifolds. These powerful heads incorporate Edelbrock's high-quench combustion chamber which promotes a more uniform atomization of the air/fuel mixture for more power. Spark plugs have been positioned closer to the center of the cylinder for more efficient combustion. Swirl-polished stainless steel valves provide maximum flow. They accept center bolt or standard valve covers, work with most stock exhaust manifolds and have intake and exhaust ports that are .200'' taller than typical SB-Chevy heads. Match these heads with an Edelbrock Vortec intake manifold for the best results.
