Edelbrock cylinder heads are chock full of features not included in competing products, such as threaded inserts in rocker stud and exhaust bolt holes and manganese-bronze valve guides with ductile iron seats. And now they’ve been accepted for Stock and Super Stock use, noted by the NHRA oval logo engraved on both sides of the cylinder head (qualification varies by part number).

Made in the USA, Edelbrock cylinder heads offer improved performance throughout the RPM range for tremendous throttle response and top-end horsepower.
