This has probably been beat to death 440 Source Stealth Heads vs. Eddy RPM 440s?

[1Bad70Charger]

I see that the 440 Source Stealth Cylinder Alum. Heads are $475 cheaper than the Eddy 440 RPM Performer Alum. Heads.
I am a firm believe that you get what you pay for but on my 1970 440 engine, built to factory specs., except for slight hotter cam, are the Eddys worth the extra $ for a street car that I am looking to get 525 Ponies out of, and 525+ ft. lbs of torque?

It seems to me with the right matched cam, intake manifolds, carb, etc., I am going to make about the same power vs. both heads.  What am I missing her and is the extra $475 worth it or not?

Thanks   and sorry if this topic has been beat to death but I am a new to this performance website and just got rid of 2 HUGE horsepower Chevys and believe I am back to Mopar for life now as I always seem to favor these more unique bad boys over your run of the mill more common Chevys!

Certainly someone has an opinion on this million dollar question?

It has been beat to death. Here is one link to read if you have not yet.

Do a search of Stealth heads and you will find more. I personally went with Mopar Performance aluminum heads. I just felt Edelbrock and MP had better quality control than 440 Source. I did use a 440 Source stroker kit and it was fine, but the issues in the above link were happening around the time of my build so I was leary of the heads. It seems the general consensus is they are good for the money, but you definately need to check the retainers and locks on the valves and most likely replace them with better ones. That is also discussed in the link provided. Good luck with your build.

General,

Thanks for the link I appreciate you finding and posting it as my computers skills are not the best when tracking down specific threads like this.  

Now I can read up on this and research from there and make an informed decision without having to continue a dead horse on this topic!

When it comes to bang for the buck power potential and all things being equal my opinion is that the Eddy's still seem to be the benchmark.

The RPM or MP 452 aluminum head would be my choice.

 pitty Edelbrocks & the MP452  version ,  did not look like the Stealth heads !!  ,  to me they look out of place under the hood ! of anything but an all out race car ! although  i even like stock looking  intakes  painted motor color also 

was/am  seriously thinking about getting a set of  CNC stealths  ,  but te jury is still out

I used a set of stealth heads. I cant give you any numbers other than seat of the pants feel. They outperformed the ported iron heads I had greatly, using my ass-o-meter as a scale. Well worth the money. The whole idea behind them is to keep stock appearing with the power advantage of an aluminum head.

[OttawaCharger]

to confuse you a little more, there is also the 440-EZ heads by Indy 

[Ghoste]

Are the 440-EZ's really all that easy though?  I don't actually know or know anyone personally who has used them so I'm just asking based on some of the other ICH stuff I've seen. (which btw, is not a comment on their quality or power production ability just the bolt on and go aspect of their heads)

[1Bad70Charger]

What is the general cost of these heads? I take it they are more than the approximate $1,370 for a fully assembled set of Eddys!

I don't think comparing INDY EZ440 heads to Eddy's is a fair comparison...The INDY's will run off from the Eddy's every time, IMO..

[Ghoste]

They better, aren't they like twice the price just for the heads?  And then you have to buy their intake manifolds?

[firefighter3931]

The basic EZ's with a std intake port window (383-440 size) is around $1900 for the pair. The max wedge port EZ-1's start around $2100 and go up from there.

They better, aren't they like twice the price just for the heads?  And then you have to buy their intake manifolds?

The std port EZ flows a little better than an E-head but they are really a max wedge head with std intake port sizing. The intake ports are max wedge internally then neck down to std port just before the intake mounting surface. The larger port volume will slow down velocity and make the engine feel lazy at lower engine speeds. Not my first choice for a street/strip 440 or a pump gas mostly street driven 500in stroker.

It's not allways just about the flow numbers.

Haven't the Indy's always been more of a racing head?  (that is to say, they were somewhat dragged in to EZ's as a compromise because of lost business to the Eddy's?)

[Cooter]

IMO, the only reason the Eddy's sell so well, is the fact that the average NON engine builder guy/gal can buy a set of Eddy RPM heads, bolt them on and go....With any head that flows well, the Victor Eddy heads require all that crazy offset rocker arm, Intakes, and headers as well..

You just don't "Bolt on" any "Good" flowing Aluminum head IMO...
There's always a trade off..The heads cost you $1600.00, then you have to buy crazy rockers from T&D which are offset, then crazy pushrods, then crazy headers...By the time you have a NICE set of Aluminum heads that flow well, you've spent around $4000.00 in the top end regaurdless of which head you go for...

[Ghoste]

Hmmm, an interesting point.  I'd agree that they sell well because the average car enthusiast can bolt them on and go but I think I would still consider them a "nice" set of heads.  When you consider the cost of refurbishing stock iron heads, the fact that you can get the Eddy's plus add a little to the performance of the car, how can you go wrong?  The Victors and Indy's clearly have their place and yes, there is a greater cost involved but the person buying those is more likely investing more in the rest of the engine too (at least they better be).
As you say, the Indy's are a different animal entirely but I think there's a room and a very definite need for both in the jungle.

[Cooter]

This is just MY opinion here, but If I'm gonna build an engine that requires ALuminum heads and all the crap that goes with them, I'm not gonna spend A minimum of $2000.00 for a "Little" bit better than a fully worked set of Iron heads as I do all my own porting, Valve work...If I spend more than $1000.00 on heads of any type, it better be one helluva reason why meaning The car better pin me in the seat and FORCE me to reallize "Oh yeah, it was worth it"....When talking aluminum heads, If I'm spending the money even in a "Street" car, I'm going full tilt...All I can get...I ain't gonna do it but one time....This is why I'm a 440 Big Block man instead of a Stroker Small Blocks @ 440 Cu. In...

   and thats what makes the world go around.  i like the looks of the eddy or mopar 452 head, acually i like the mopar head better because i like the mopar logo on the front.   on a side note, why did elelbrock put the the logo on the small block heads vertical?

Tell me about it!!!

I was made in the USA. My Charger was made In the USA. My engine including the Eddy heads were made in the USA.  Letters matching car / owner ?
