It's nice to see someone use something other than a small block Chevy once in a while.

From that same thread... (one source anyway)

for comparison:

iron "346" open to about 203cc 2.14/1.74 backcut valves
template port pushrod pinch opened:
100---122---62
200---154---104
300---199---130
400---230---147
500---240---161
600---250---168
source: Mopar Muscle

parts are essentially the same as the stealth heads w/ a smaller intake port.


The Source #s

100 --- 65 --- 57     
200 --- 135 --- 108
300 --- 191 --- 140
400 --- 227 --- 159
500 --- 242 --- 173
600 --- 254 --- 183
700 --- 261 --- 191

Information is slowly starting to leak in now

[mally69]

What we really need is a comparision between     edelbrock OOTB    and     stealth OOTB.. 

[Musicman]

There's scores of people running 10's and faster with edelbrock heads.

Nobody ever complains about the Edelbrock's flow, now someone flows our heads, clams they flow about the same as Edelbrocks on their specific bench, and people respond saying they're "barely better than a stock 906."

When the time slips start coming in of people running single digit et's with these, the proof will be in the pudding.



Brandon---this will happen soon--"we" in the midwest are stuck in our houses with 2 degrees.

---waiting for CA racers to post ET's.....

Sounds like Brandon has been taking a bashing just because the heads flow similar to Eddy's out of the box... (ooohh, big surprise there) I don't get it, what's the beef???

Weren't they supposed to be the same thing as eddy rpm aluminum heads?        
          They are the same as eddy rpm heads, right?   why is someone saying they are same as stock iron heads,
                  that must be wrong,

Oh my god, has he ever taken a bashing, you should have seen some of the posts over there before they got deleted, it got plain nasty.  All I can say is, I appretiate the effort from him to do this. It takes alot to even try to do something like this, money time etc.... I think his product will sell.

[Musicman]

   You can please some people some of the time... and who cares what the rest of them think... let them try and do better... At least Brandon has stepped up to the plate, and thrown the ball.
I'm still waiting for more information since one bench test doesn't mean much of anything anyway. Besides which, flow numbers are nice, but the proof is in the pudding. There are a number of heads out there on the market for Chevy's etc, with great numbers that aren't worth squat.
Bottom line... if they flow as good as Eddy's or even close enough... and they make good power across the board, then I'm happy... you know why? Because mine cost a lot less... so if I do feel they need a little port work, well I'm still ahead of the game!

[aifilaw]

yeah, those flow numbers mean nothing to anyone unless you run them on a calibrated bench, or you run them side by side on the same bench at the same time and under the same conditions as something that is known (eddys)

[mally69]

 Dwayne Porter is also going to flow a set of stealth heads from brandon, I can't wait to see what he comes up with 

[Paul G]

I dont understand those guys. 440 Source put out a set of heads ready to run with great improvements over a stock head for $900 and there complaining about the flow numbers which aren't bad. What do those guys think they are getting for that amount of money?

[aifilaw]

It looked to me like someone flowed the heads on an uncalibrated bench, an got around 230 on the intake. And without thinking people correlated that flow to an iron block, which on a calibrated bench runs around the same, and thought they were getting basically a garbage head made of aluminum. Even when teh poster pointed out that the stock edelbricks flowed around 230 on that same bench... Therefore, its my guess that the stealth heads truly flow around 290 on the intake at lift, and I believe we'll see those numbers once its run on a calibrated bench. Miscommunication at its best.

No, they aren't the same as Edelbrocks or stock heads. Externally they look pretty close to stock (as opposed to the Edelbrock big-block-of-aluminum look) but they are aluminum instead of iron. Lots of guys are excited to get the benefits of a new, better flowing head that appears factory along with the advantages of aluminum (less weight, higher compression, etc.). The price is also about $400 less than the Edelbrocks and typically less than doing a bunch of machine work to old, fatigued iron heads. I'm no expert but, from reading those posts, they still flow a lot better than stock and nearly the same as out of the box Edelbrocks. Mainly what people seem to be missing is that these are designed to be bolted on and have a stock appearance - they are NOT a race head! Who cares if you can get an extra 5 CFM when you're sitting in traffic at the cruise-in? If you want to race then you likely wouldn't be looking at these heads any way. Mostly people are just blasting Brandon because the heads aren't made in the US. They will never accept the product even if the performance was ten times better than anything else.

Of course, I did find it funny that a stock small block Magnum head flows about the same. That's technology for you...

Yes, that was one of the other selling points that many folks have overlooked...glad you brought that up.

[defiance]

Having just plunked down $900+shipping for a pair of these, and those being ootb flow numbers, I'm pretty happy   Now let's see what Jeff @ MCH can get them up to

[firefighter3931]

The guy that posted the numbers originally said that they are equivelant to an Edelbrock RPM head....on his  bench. Flow benches, like dynos will vary from one to the other so these numbers don't mean much to me other than they are basicly the same as an RPM head. Heck, those are waaaay better than a stock 906/452, have a closed chamber and won't crack....what more could you ask for ?

Like Troy said, these are not a race head....just a hot street "replacement" type casting that has some potential. Heck, a 250 cfm closed chamber aluminum head will make 500hp with minimal effort, on pump gas with no detonation issues. 

When Dwayne at Porter Racing Heads gets them on his bench then we'll have the real skinny on the Stealth heads.

For those of you that won't buy these heads because they are not made in America, can you say you don't run foreign gasoline through your American made heads?  How much money do you give to the Middle East compared to what you give Edelbrock?  I'm getting a set now without a motor for them just because of the crap the Source is getting.

gotta be the dumbest reason to buy a set of heads. 

[Mfr426]

So, has anyone bolted these new heads on and ran their car? Just wondering how they made out before I pull the trigger...

[mally69]

I just ordered a set last night, I wont have them for about 3-4 weeks yet...

[SeattleCharger]

Here's the ticket.      (c) mally69 (tm)               Just get a 512 stroker and put all this on it,  gonna check my lotto tickets today,
