Should I go Indy EZ/440-1, RPM Perf, Victor or Stealth Heads??????

[68 Bullitt Charger]

Have a question guys......

In your opinion's what is the best(performance) Head for serious street performance and occasional track outing's while on pump gas and somewhat nice street manner's. Looking to make 600hp/600lbs Trq in a 68 Charger with a 4 speed and Dana.

Trying to decide my best bet for performance using a roller cam in a 505 stroker around 10.5 comp, just need to decide Heads. Cost is not a concern as I want the best bang for the buck. The heads I'm looking into Indy EZ or 440-1, RPM Perf, Stealth and Victor. The head I purchase will be CNC ported,etc.

Please guys what should I do......

Thanks, Joe

if you want the best...i would go with the indy heads. the 440-1,s or the sr,s. i have 3 sets of cnc sr heads on 500" motors. all make about 700 hp-650 tq.......the sr,s would be a better head for the street.

I cannot give an opinion without understanding clearly what you believe is "nice street manners", "serious street performance".  And finally, what specific track performance are you looking for in et and mph? 

You can easily get to the 600 hp mark and into the 10s with ported Eddy's or Stealth's on pump gasand will meet some peoples definition of nice street manners.

Just my opinions, no wars wanted....
When you say "Roller" Cam, you are intending a "STREET" type Mechanical Roller profile...... correct ?
NOT...
a "RACE" Roller profile, or Hydraulic Roller.

Brians absolutely right IMO here...
On a 505 for 600/600, I'd just cut to the chase and go with the INDY EZ CNC Head, real eazy peazy at those power levels.
I routinely see 625hp/650 Trq out of my 493 packages with EZ heads, using STREET friendly Flat tappet Cams on Pump Premium.

The EDDY/Stealths can be made to work,(with enough $$ for Porting),
but really,
it's at their outer limits of development for Power production on Pump Fuel Compression Ratios, and "tamer" Camshafts for street useage.

Hi Guy's, Thanks for the opinion's and all are welcomed advise. As far as what I'm looking for in street performance and manners then the occasional track. If I can get the car high 10's low 11's, pump gas, 4 speed, Dana in a heavy Charger that would be cool. I am not going across Counrty although I will drive around to show's and cruise nights. I have a HP 440, Scat stroker kit, JE Piston's and a Hyd Roller Cam (600/620 235@50), lifters and 1.6 Crane Race roller rockers. I hope this spells it our more as to what I'm looking to do.

Thanks again Everyone,
Joe NY

High tens in a heavy street stick car, especially with a street clutch, is going to take about 75hp more than an auto car would. Keep that in mind. 600hp is easily doable with Eddy heads. I'd build a 4.25 stroker RB with CNC Eddy Performers and a Performer RPM intake  and a comp hydraulic roller and call it a day. I did a six pack version of this and it made 625hp 680ft/lbs on the dyno on pump gas.

Joe, for your type of build i would recommend the Indy EZ-1 cylinder head. That casting will make 600+ horsespower/torque pretty easily in a mild pump gas configuration. 

Here's a good thread to read through. The original build used a 500in stroker with Eddy RPM std port heads and made excellent power 

http://www.dodgecharger.com/forum/index.php/topic,36197.0.html

Then John decided he wanted more power so the cam and top end was updated

There are specific build details along with dyno results so this is a comprehensive and detailed post worth looking over !

Nice threads Ron, thanks for digging them up.  I would however, caution readers to observe the significant difference between the two, and there would probably be 40 hp or less between them in an apples to apples comparison.

To the OP, that cam is pretty small and leans more towards mild street manners verses most performance.  I don't know if 600 hp is achievable, but 11 sec ets would still be pretty easy

Hi Ron, Thanks for digging those build's up. I copied them as well as read all the other opinion's from you expert's. You should know how appreciative I am for your advise and time. It will not go to waist. I have to say, Ron that build seems to be the way to go. Lots of Torque/Power. You guys are great. Thanks, Joe

IMO,
At this point anyways, far more needs to known about the entire combo you are planning, if your goals are still the high 10s low 11s as stated.
Things like the Fuel System, Gearing, Tire Diameters, etc., etc., are all important.

A few things that are known at this point, IMO, should be up for discussion if high 10s or low11s is still the goal....
* 833-4 speeds are inherently slower than autos and hard to shift at those ET`s for sure, hard on parts at best, and IMO, and complete waste of time for those goals....been there...done this a hundred times with my Customers...all the same result...eventually if they want to get THERE( High 10s low 11s), Autos get installed !
* strokers eat up Cam duration very fast...a 235* at .050 Camshaft is doubtful for those ETs or that power level on ANY Cylinder Head, just plain too small.

Very tough to get the best of both worlds, that being GREAT street manners, and still being capable of High 10`s Low 11s in a 4,000 lb car.
No offense intended here....
but the 833 4spd if that is your intent, and THAT Camshaft....are more conduscive to high 11s and low 12`s in a street configuration 505, still a good ride, and be happy.

FWIW, 440 Source has a new head out. Bigger ports, many improvements. Looks like the issue of needing a ton of porting may be a non-issue with these heads. I haven't heard any reviews about them yet though.

The Super Stealths still use the same Valve length as the Regular Stealth.....
meaning....
potential Bowl Volumes above the Valve are the same, which leads to the same pitfalls with plug wash, etc., as the regular Stealths past a certain point of development, because there just isn't enough "Time" for the added Airflow to turn and make the Valve.

Nice of them to straighten the Pushrod Pinch in the port though, and now using .650" offset Intake Rockers, but, I just can't see investing for the further R & D, read $$$ in a "budget" head ??
Probably great for those Guys who just gotta have a "stock" outwards appearance...

same old story for me.....
IMO, just plain better to buck up for a better Head at the start ?
