I’d look at the E streets and have Dwayne porter true them up. Should do what you want and be a nice package. Straight plugs too. He can clean up the little things like tight valves and it doesn’t cost all that much. Was going to do a similar build myself until I decided the project took more time overall than I had to invest. I talked to him about it that was the direction I was going to go.
I want my fair share

I have them on my 451, I think they work OK. ET in signature, it's not the best, it's not the worst. Here is a less than perfect 1/8 mile pass: https://www.youtube.com/watch?v=nDsPTMzmFNII had the valve guides honed to loosen them up slightly, I removed the ridges right behind the cnc gasket match, I had a 30 degree backcut put on the intake valves for more flow, and that was it. The seats on the heads still have Edelbrock's valve job on them. Maybe their machine work has slipped, I don't know, but mine were okay. I just wanted to tweak them. These forums are way better for a fella looking for advice than any of the Facebook groups, and the RB only group is in my humble opinion probably one of the worst offenders for horrible advice. Call out an incorrect statement, nobody sees it. You don't actually need aftermarket heads at all for that power level, reworked iron heads will do that all day long but aftermarket heads will make it easier to get there and will save some weight. It also might cost nearly the same. E street or RPM heads would be fine for what you want to do, and will allow a little bit of growth.

Years ago I bought a set and bolted them on out-of-the-box to my very worn, warmed-up 440. Picked up .2 in the 1/8 with no other changes. The next year, I built a 500" engine and had Modern port the Eddies for it. The primarily street car would run 6.8s in the 1/8 like that. I still have that engine.
What's not to like?
Master, again and still

I have no problems calling them out there but their excuse is always "I've been doing it like this for 50 years!" or they just don't respond at all. I'm about ready to unsubcribe from every Mopar Facebook group because all they do is raise my blood pressure.

I have had many different sets of heads in my racing years, no problems with Eddy RPM heads yet and I don't know anyone out here west of the rockies that have had problems with them either What I have learn from the internet is there are more want to be racers and "engine experts" nay sayers, haters, than there are those that do use them with no problems, no matter what the product is

I'm about ready to unsubcribe from every Mopar Facebook group because all they do is raise my blood pressure. Agreed, It's pretty ridiculous at times. Like I mentioned about ballast resistors! On Facebook, the ballast resistor seems to be the reason for everything that ever happens to a vehicle. At some point I'd like to think there would be a backlash and a return to the forums, but it seems this old format is, for the most part, only preferred by old people.
