I think the Edelbrock 84 cc heads and some mild porting would be just what you need.

Hey all,
I am ready to upgrade my 1970 Challenger to aluminum heads.
With all of the after-market heads out there now I’m running in circles with what to go with.
So I am looking toward the Mopowed knowledge of you all on the Moparts web board for the correct parts the first time.
I also want to run a roller camshaft and roller valve train. So I am also asking for input on what to run there also.
The current set-up is as follows –
Motor –
- 1969 HP 440 block w/stock steel crank
- 452 heads (gasket matched) with stock valve train
- M1 intake
- Hooker Headers (3 ½ collectors)
- Main stud girdle & windage tray
- Demon 880 carburetor
- Holley Volu-Max fuel pump
Car –
- 1970 Challenger
- Dana 60 w/4:10 gear
- Mini tubbed
- Stock suspension with 90/10 front - slightly too long in the rear
- 29x12.5x15 Hoosier quick time pros – 3.5’s up front
- Box tube sub frame connectors
- 6 cylinder torsion bars
The car was on a RW Dyno and made 398hp and 486lbs with a 750 Holley
The best pass on the street tires and full exhaust was 11.89 @ 120 with a 1.61 short time.
I believe that covers everything, any and all help and opinion would be greatly appreciated!
Thanks, and remember . . . Do it in a MOPAR!!!
What cam are you running with the 11.89 at 120
combo? The 120 is a good speed to maybe hit
the mid to high 10's.
You say opinion, so this is what I think. No need
for a roller set up unless you want to spend the money.
A solid cam will make very good power at
a better cost than a roller. I also think the
440source CNC'd Stealth heads will do the trick
with simple Iron ductil adjustable rockers.
I had a combo close to you. Demon 825 Race carb,
M-1 intake, 452 iron (full ported) heads, Hooker
super comp headers. I had the Ultradyn .613 solid
cam. In a 4000 lb. car it ran 11.16 on Hoosier
QTP's. All in a little 440.
Snap your neck, mega G-force launch, is all I want!

Only reason I didn't mention the Stealth heads is that I've never seen a set or used them,and usually there is a big -discussion about them.But the Stealth heads would work great too.

I bought a set of 440source stealth heads for mine on their first production run. I just bolted them on for the first time this week and have not run them yet.  I know, I know, took me forever to get around to this project. If I had to do it over again I would run stock heads and try a centrifugal supercharger with a mild hydraulic cam, but that's ansering a question you didn't ask, lol. One thing I like about the stealths is after I painted the motor, at a casual glance they look like stock heads. Get up close and you can tell they're not stock because the casting lines and machined surfaces are too crisp.
