This part number includes "CNC Super Prepping" of a pair of new Edelbrock RPM 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 up to 627HP.
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 puhrod length checking tools in related items.
Closed chamber heads are approximately 75cc stock and 83cc after porting
If you need a combination not shown here please call
Valve springs, retainers, locks and seals are the stock Edelbrock parts
