The Edelbrock E-Street 70cc cylinder heads are a pair of American-made heads for 1955–1986 Small-Block Chevy engines, designed for entry-level street performance in the idle-to-5500 rpm range. Featuring as-cast intake and exhaust ports and modern combustion chambers, they increase airflow and combustion efficiency while offering an affordable upgrade for classic Chevy street builds intended for pre-emissions vehicles.
