The Edelbrock Performer RPM SBC 64cc angled-spark-plug cylinder head is designed for 1955–1986 Small-Block Chevy applications, offering improved airflow and drivability for street and rod builds. These complete heads retain stock compression ratio while providing valve-spring and porting upgrades suited for flat-tappet cam use, and the angled plug layout promotes more efficient combustion in compatible small-block Chevy installations.
