Edelbrock E-Street vs Performer RPM Heads

DC Dart said

How much port work do the Edelbrock heads need to match the trick flows OOTB. I know it's likely cheaper to buy the trick flows for the given flow advantage. But can these E Street be made to flow like trick flow later on? Within reason I guess. Yeah I know define reason right. LOL

Flow rates aside--You cannot match the gorgeous chamber on the TF's or there sweet intake valve shape which in large part results in the killer .400"-.500" flowrates. The most flow I have personally achieved with an Eddy 5090 and the stock valve was 298.5cfm @ .600" . With a bunch of other trickery these went on to support 680hp 654tq on a 469BBM though and got us within 4 points of 2nd place in the 2016 EMC. The good ole days. J.Rob
