This part number includes "CNC Super Prepping" of a pair of new Edelbrock E-Street heads. The CNC /Super Prepped head work includes our proprietary racing valve job and seat grind that improves valve and seat sealing and airflow. A deep port match is done to blend the intake and exhaust ports better. The intake stem heights are equalized and the exhaust valve stem heights are equalized. On top of all of that we perform C.N.C. combustion chamber work that is specifically designed to increase air-flow by un-shrouding the valve. 

This chamber work opens up the chamber by approximately 8cc. If you need them milled back to original or a certain cc, let us know and we can quote you a price.

This level of head can support approximately 650HP.

  • After porting, valve seats are finish machined with a multi-angle valve job.
  • Light-weight aluminum castings (approximately 29.0lbs each, assembled)
  • Accepts standard "B/RB" intakes and exhaust headers (factory exhaust manifolds may require modifications)
  • Adjustable rocker arms must be used with cams having greater than stock valve lift. We recommend Hughes Engines adjustable rocker arm assemblies, along with matching pushrods. See pushrod length checking tools in related items.
  • Closed chamber heads are approximately 75cc
  • If you need a combination not shown here please call

  • NOTE: This head will need to be machined for clearance if used with a MSD Ready to Run distributor.

    What's the difference in an "E-Street" head and the standard "RPM" head?

    1. The E-Street head uses a less expensive (a little heavier) valve than the RPM head.
    2. The E-Street head has powder metal valve seats whereas the RPM heads use ductile iron seats, which in our opinion is a better seat material - it is harder and lasts longer but is harder to machine.
    3. The E-Street heads do not get hand blended valve bowls from Edelbrock. The RPM heads do.
