Edelbrock E-Series and E-CNC Cylinder Heads Now Available at Summit Racing

Looking to step up to a better cylinder head? Edelbrock now offers two aluminum cylinder head series that are worth a look. Maybe even two looks. All Edelbrock cylinder heads are cast, machined, and assembled in the USA.

E-Series Cylinder Heads for Small Block Chevy and Ford
The E-Series heads are a step up from Edelbrock’s E-Street line. They feature larger runners for increased airflow plus revised exhaust ports and larger diameter springs for higher lift camshafts, making them ideal for larger displacement engines and spec racing classes. The E-Series heads also have as-cast ports and retain the stock exhaust port locations, making them compatible with OEM headers and hardware. The heads come fully assembled with valves, valve springs, locks and retainers, rocker arm studs, and guideplates.

E-210 Heads for Small Block Chevy
• 210cc intake/75cc exhaust runners
• 64cc combustion chambers
• 2.080” intake/1.600” exhaust valves
• Choice of 1.460” single or 1.550” dual valve springs

E-205 Heads for Small Block Ford
• 205cc intake/62cc exhaust runners
• 60cc combustion chambers
• 2.080” intake/1.600” exhaust valves
• Choice of 1.460” or 1.600” dual valve springs

E-CNC Cylinder Heads
The E-CNC cylinder heads have fully CNC ported runners and combustion chambers for maximum horsepower and torque. They’re ideal for high performance street and light duty racing applications. The heads also feature lightweight valve springs and heavy duty hardware for maximum lift and maintain the stock exhaust port locations.

The heads come fully assembled with valves, valve springs, locks and retainers, rocker arm studs, and guideplates. They’re available for small block Chevy, big block Chevy, small block Ford, and GM LS engines.
