Yes, the E head is the best bang for the buck. Just make sure you check them closely, especially the valve job. I have bought three sets. Of the six heads, five had the intake seat narrowed to only ~0.020" by the relief cut in the deck. These were for my own engines and I do my own head work, so other than the irritation of Edelbrock's response to my complaint, it wasn't a major problem.
Like most everything in the automotive performance world, they aren't actually ready to "bolt on and make horsepower right out of the box."
I used Stage V heads on a customer build before the Eds were available. It took a lot of port work to get the flow numbers to where the Eds are out of the box. But I really like those Stage Vs.
I don't know what Ray Barton charges for a set of prepped Eds, but it might be worth investigating.
