Has anyone done a comparison dyno between these heads? I am still reading up on info for a 360( possible 408 ) build and was wondering about the pros/cons of using one vs. the other. I know the Eddy heads probably weigh less but was wondering if the the LA-X heads might be the better bang for the buck?? Of course with 2.02 valves the LA-X heads are 1075 assembled so there is not a huge price difference.

Brian of IMM sells a RHS/IMM small block head like that with a his own 4 angle valve job blended, beehive springs, etc that flow more than Eddy heads out of the box. These are the heads that are on the 408 motor that is in Car Craft. http://www.immengines.com/rhsheads.html and http://www.forabodiesonly.com/mopar/showthread.php?t=101248

With the IMM heads you get hands on personal machine work as opposed to production type stuff of the Eddy. But the cast iron heads do weigh more.

The choice is yours.
 
Both heads will work well when matched with other components in a build. Both have up sides and down sides. I prefer aluminum but iron's cheaper. It's really up to you and your builder.
 
Autox is right, and thank you! The only 2 downsides I can see are the weigth which is a non issue for a street car or bracket car, and the other is future upgrade.
The head we sell, we sell like that for the best HP per $$$ value. Yes they can be ported, but your not going to gain alot of power...it will be minimal like 20-30 tops!
The OOTB chamber and exhaust port is MUCH better than the eddy head and the intake port the way we sell it outflows the eddy head on avg. by 30 cfm...AVG!!
Price the eddy head with a good valve job, beehive or good double springs, and port work enough to match the RHS head we sell...HEAVY never looked so good!!!!!!!!!!!!!!!!!!!!!!!!
LOL!

Can't you have those guys pour some in aluminum?!? Are they casted in Australia?

Did Dan at DC Performance get ahold of you?
 
Doesn't the cast iron heads hold up better--take more abuse? Like the motor running hot cause you got caught up in a traffic jam-or those one red light after another. After a hard run if you need to stop or creep along for 5 mins later its easy to see 210 water temps.

I had my MP cast iron heads on for 3 years and had the temp red gauge (msd) go up to max 250 a few times over the years--yeah I know but like nothing ever seem to go wrong. Would those Eddy heads took that type of abuse without needing to be pulled and milled flat again?

One other thing to consider, that nobody has mentioned in this thread yet, is that iron heads hold heat in the combustion chamber much better than aluminum. And combustion chamber heat equals power.
I've always preferred an iron head for either street only or street/strip car.
Brian, I'll be in touch as soon as I get the money saved for your RHS heads.
 
Theres is no comparison one is a iron head the other is an aluminum head...
 
Coatings help to minimize/neutralize the difference between iron and aluminum, performance-wise.
If your engine is overheating in traffic then it just isn't right. The fact that your engine overheats means that either your engine is not properly tuned or your cooling system isn't up to the task or both. This should be fixed, not used to sway you towards iron or aluminum heads.
 
I bought "Eddy's" for a 5.2L, before the RHS heads were well known. It "looks" like alum. head has a faster burning chamber. Some contend you can run approx. 1 point higher comp. on same octane. This should equate to higher torque/hp. ,somewhere in the rpm. spread ? I needed the reduced weight, to replace a /6 and keep the orig. torsions and better corner burnin. How is the RHS head flow #'s, "out of box", when it's got 4 angle valve job and bowl blend? While we're no longer, out of box, what do the Eddy's flow, with moved int. pushrods? 2cents, Ateam.

...and what does one's butt hole flow with their head pulled out of it?
ha ha gimmie a break..'movin push rods' ....

they r ootb when consider you get them bare or with valves...

so IMM puts the vales in and does the VJ just like indy would do, except brians version flows more!

btw
I like how ya went from putting valves and a VJ on the iron..
to 'moving the push rods'

that crack'd me up!

Very well put...trust me your running the RIGHT heads,especially if you ever want to upgrade them...

more stupidity...

Hey mind reader, whats his combo again?


LOL

someone could be half way around the world saying eddy heads aren't all that, and this guy would show up to defend'em. HA

Your so loyal.....ahhhmannnn
ol victor gonna buy you a pearl neckless for this. :cheers: HA AHAHAHAHA AHAHAHA A AAHAHAHAHAAHAHA AAAAAAHAAAAAA.......

thanks for the entertainment!
 
ya know....it would have fair 4 u to say..'ya got good heads'' or ''ya got light weight heads'' or even you got good light weight heads that will handle point more compression on the same octane, cause at least thats true.

but to say he's got the ''right heads'' without even knowing his combo is well...do your farts resemble your voice by chance?
 
A-team, might I suggest you start your own thread.

Brian's prepped LA-X heads kick the snot out of the Eddys. To get similar numbers from an Eddy head, you're going to pay an additional 400-700 in porting depending on who is doing it.

If I didn't already have a pair or two of eddy's ready to run, I'd buy the LA-X heads, especially for the 360 I have.

LOL..theres those of us that have Edelbrocks and know exactely what they can do,and what they can be.. and then there's people like you that don't.LOL.ha ha ha ha:thebirdm::thebirdm::thebirdm:
 
There are guys that run eddelbrock heads and then there are guyz like stroked340 who run eddelbrock heads.

the diff between stroked340 and them is they are good guys that know it can be done different ways and it doesn't take big $$$$ and aluminum to do it...it was there choice and rightfully so..
while stroked340 thinks these heads are the holy grail and the stuff dreams are made of.

I say his dreams are made from crack induced 'strokes' , hence the name possibly..LOL

r we having fun yet? lol
 
My combo has been listed several times on this site no big money spent,just the RIGHT people doing the work including me..theres those that have aluminum heads and those that are still using 40+ year old door stoppers..lol...

you say they are 'barely touched' or 'very lil porting'

I bet I toss on a set of ported J heads and you'll run the same or better with the exception of the weight affect on et/60, a 10th if...

btw
my dad can beat up yer dad...so neener neener:toothy10:
 
Another post with the same 2 individuals going at it.....:argue::boxing:
 
and a iron w-2 setup from 1976 would produce more power than he's got now! lol
