I know if I were deciding on what heads to use on my hemi, to put in my 4175lb strictly street car with 3.54’s and OD unit......... really big flow numbers would be right at the top of my list of “must haves”.
You neeeeeeeeeeed 400+cfm of flow available when you’re racing along at 2100rpm.

Dang Dwayne, is that a bit of Yankee Christmas sarcasm!??! My Mopar aluminum Hemi heads were CNC ported by Modern and by the sheet flowed 446 cfm on the intake, 261 on exhaust. Theoretically, they could support 1000 hp. Looking back, I could have met my goals with less flow and made the same hp at a lower rpm. I quit racing several years ago, so it's about a 99% street car now. Like most of us, sometimes you get carried away looking for max hp. If I were in your shoes, knowing what I know now, I would send them to Dwayne and have him port them to a level that is commensurate with your goals and use. Nothing wrong with the Mopar head, if your guides are good, porting and a good valve job and you are in business. If you just want the edelbrocks, by all means, get them. I sure never discourage anyone from spending money! I know I am good at it! Let us know what you do, this has been an interesting post!

Dang Dwayne, is that a bit of Yankee Christmas sarcasm!??! Huh?whaaa?? Noooooo........ he wants to buy some new Edelbrock Victor heads(the series of heads they offer for race engines) for his strictly street car......... and I’m just being agreeable. It’s his car, his build, his money...... his decision. If those are what he wants....... he should just buy ‘em. It’s certainly easier than boxing up your old stuff, shipping it out...... waiting for it to come back, etc. One call to Summit and a couple days later...... boom..... new heads are at your door.

You neeeeeeeeeeed 400+cfm of flow available when you’re racing along at 2100rpm. Really? Are you being serious? I value your opinion very much. I know that at cruising speed the air flow does’nt matter. But last year at our “Moparts” Mike Bucle asked me to race his HEMI Coronet just for fun. I would like to take him up on it next year!

I ran across this in my travels/research. Maybe it will help you...hopefully it doesn't add to the confusion. Pretty sure this may be the flow sheet from my heads I've posted here a few times. They are the normal MP aluminum street hemi heads CNC ported by MCH. Make well over 800 hp on pump gas on my 572" hemi.

The OP's original question seems like a simple one to answer. He wants the best performing head. And although he didn't mention it, he probably wouldn't be opposed to the least cash outlay to get there.
I got the same flow chart that Zippy posted with my heads that MCH did a few years ago. It would be easy to price that port job today from them or from Dwayne.
Then somebody surely has a flow chart for the new Eddies. And pricing them is no problem.
Comparing flow to dollars should make the right choice clear.
And if it matters, the ported MPs on my 540 have great street manners. 250* cam, Indy dual plane intake and a Thumper Dominator top it off. It starts right up, has a steady idle, and drives with no bad habits. My point is that the 400ish flow is not a problem on the street.
I personally think that it is important to have a Hemi (even a Hemi that doesn't see much racing) to run like a Hemi is expected to run. Nothing is worse that to pull up beside a brand Xer and not be able leave him in the dust. The few times that I have had a race, my Hemi had upheld the Hemi tradition. That is worth the price of admission.
So, I say 'go for it', OP. Help that Hemi run like a Hemi! And when you can do it for a bit less money one way rather than another, and have good street manners, too....what's not to love?
Master, again and still

I’m not really lobbying for the job......... and if I ported them they wouldn’t flow anywhere near as much as the flow sheet posted.
Since Dave has had such good results with his CNC ported heads from Modern on his mild combo, that’s probably the best bang for the buck for reusing the current heads.
Or sell em and buy the Victors. The Victors flow right at about 400ootb.

Once a guy has that beast, I feel it had better be capable of running respectably hard, staying in context with the rest of the vehicle.
