This chamber work will open the chambers to a larger size. If you need them milled back to original or a certain cc, let us know and we can quote you a price.
Heads are reassembled using the Edelbrock supplied stock springs,seals, locks and retainers.
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.
