Dont forget about the newer MP/Edelbrock castings

These things flow a ton, and are the best thing out there for a hemi head that is a true SR type deal..stock valve angles, and port locations..

Modern cylinder Ported mine and got 460cfm from them.. The SR Stage V's wont flow that

I have all kinds of pics, and flow sheets..PM m if your interested I will email them too you.

Don't be so sure the sr stage v's wont flow that.
My FHO CNC'd stage v's flow that
Contact Tim and he'll steer you in the right direction.

Here is the flow data of my Modern Cylinder CNC Stage V standard port, standard valve heads:

"i was shocked by these numbers on the intake just as much as anyone looking at this,, this thing was wayyy good for a 2.250 valve.

superflow 600, 4.320 with bore notch, 28"

intake 2.250
.100-78.5 cfm
.200-162.4
.300-257.5
.400-342.4
.500-396.5
.600-422.4
.700-440.7
.800-450.6
.900-456.5

exhaust 1.940
open at flange/2.0" tube
.100-69.0/70.5
.200-146.2/152.4
.300-178.2/185.0
.400-208.4/220.8
.500-239.5/255.6
.600-259.1/274.0
.700-268.7/286.7
.800-273.7/293.6
.900-278.7/297.3


this is a std low exh port and a std int opening, its a good sized port but with only two pushrod tubes in the head, #1 and #5 exhaust. ferrea valves.

Never said they wouldnt flow...I will stick to what i say on the edelbrocks....Here is some flow numbers beside each other...same bench also.

I wasnt really trying to run down anyones head, just trying to make a point. These heads are a great casting, much better than the older MP problems with common quality control trouble.

I also know that these were flowed on the same bench and probably same operator also. So IMO they are a decent comparo.
Looks like they are a hair better than the Stage V's, probably NOT worth a small measurable amount of power...maybe..

These also have stock valve sizes. port locations, valve angles etc.

Uhhh.. yes you did
Modern cylinder Ported mine and got 460cfm from them.. The SR Stage V's wont flow that

---

These didnt did they so whats your point?

Quote:

My point is that stage v SR replacement will flow as good or better in stock configuration than edelbrock/mopar.
You stated they will not and that's just not true.

---

hmm really..
looks to me like there down 10+cfm in the upper lift range in this particular case doesnt it..

I know what your saying...I see people recommend Stage V's all the time..im sure they are a good head. I know some people have had trouble with the older MP heads...
I spoke with a known SS/AH engine builder/racer before i was buying hemi heads, IIRC I hate putting words in any ones mouth but the guy liked the Edelbrocks, and most of the SS guys run the cast iron version (not that these ports even comes close to the stock ones lol)..In a nut shell he liked the new MP castings pretty well.
Again I wasnt trying to run down or talk bad about his, or there heads etc..just saying that Ma Mopar has some nice heads out that are just as good flowing...and guess what over $500 cheaper assembled....
I got mine through WestOaks delivered for $2300 assembled.
I have $3000 in these heads complete with CNC porting..End of the year port deal for $750, and I sold the supplied springs and retainers for like $150, and upgraded to 10 deg stuff etc.

These are also duel plug ready.

OK I give..lol you win

I wasn't quoting defbobs heads. His heads aren't SR stage v's
I guess you didn't see the post of numbers copied from the FHO website.

FHO CNC Ported Stage V Replacement Heads. For mild to wild street strip engines.
This is the standard aluminum head used on all FHO hemi crate engines.

Exhaust Port with 1.90" Valve
Intake Port with 2.30" Valve
Flowed at 28" without tube.
Flowed at 28"

.100" 61 .100" 75
.200" 135 .200" 159
.300" 187 .300" 248
.400" 230 .400" 315
.500" 258 .500" 384
.550" 267 .550" 412
.600" 279 .600" 435
.650" 287 .650" 453
.700" 295 .700" 467
.750" 298 .750" 469
.800" 301 .800" 471

It's not a pi$$ing match on who is right. Just trying to have a conversation on hemi heads
Your blanket statement on stage v's IMO is not correct.
I'm glad you happy with your edelbrocks.
I'm happy with my stage v's.

Due noted..
Those flow bench numbers compared to my numbers doesnt mean squat.
million dollar question is what would my heads flow in FHO bench?
See our heads were on the same bench, thats a much better comparison, why try to compare two heads from two benches, thats why i was looking at his heads...
