I'm in a dilemma between E-Street Heads and RPM performer heads. What is REALLY the big difference and would I feel any difference? Mainly used for the streets and if someone can briefly describe what the difference between the different intake clearances, etc.

hahah Sorry. I know it's probably late too. ha I don't know. Well, basically, I'm seeing what would I lose or what would I gain. They are both aluminum heads but is there really any comparable difference between them?

Just seeing if anyone knows if there's a big difference between these 2 heads in HP/Torque outcome. I found some guy selling new ones for 859.00 for the E-Streets.

Here's the difference from HotRod:
Affordable Cylinder Heads - Edelbrock Aluminum E-Street Heads - Hot Rod Magazine

"The E-Street line is marketed for applications under 400 hp and 5,500 rpm. The heads appear to us to use Edelbrock's Performer RPM castings but without all the finish work and hand-blending used in the higher-cost heads. Less costly valvetrain components are used, though features such as Helicoiled rocker-stud bosses are retained. The main things limiting the rpm potential are the valvesprings, which are intended for small, flat-tappet cams; they're 1.250 in diameter and cannot handle more than 0.550-inch lift (in fact, we'd keep it closer to 0.520). Machining would be required to install larger-diameter springs. The E-Street heads are not smog-legal, as the Performer heads are.
At press time, Summit Racing's nonsale price for a pair of fully assembled E-Street heads for a small Chevy was $949.95 and the Fords were $973.95. That makes them $170 to $239 less than a set of Edelbrock Performer heads."

Really depends on if you want to increase power later it looks like, the E-Streets would take more money than the difference to the RPM's to make on par with. If you're stopping at a street car and won't go with a cam >.500 they may be Ok but you get what you pay for <$ = <hp.

Dang out of more than 60 views, I got an answer. haha Thanks. The reason why I asked is because I'm going with the whole top end kit, but piecing it together which I think I can be doing it cheaper than buying the kit itself. So I am definitely doing cam, intake, carb, but seeing if it is worth getting the E-streets or get something a little more sturdy like the rpm performers. Thanks for the feedback.
