Looking to step up to a better cylinder head? Edelbrock now offers two aluminium cylinder head series that are well worth a look. Maybe even two looks.

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 ‘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 guide plates.

210cc intake/75cc exhaust runners

64cc combustion chambers

2.080in intake/1.600in exhaust valves

E-205 Heads for Small Block Ford

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 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.

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