What heads are out there that will match or exceed my EQs that are bowl ported with 2.02 intake valves? It would only be worth it to me to upgrade to aluminum if i can transfer my current valvetrain parts from the iron EQs. Whats ou there? Anything that is better with the same work done?
Aluminum heads that equal EQs for power?

Dunno your flow rates exactly.
Edelbrock Performers or Edlebrock Victors come to mind.
Hughes has a lot of head flow tables on their site that shoudl be useful to see what is what.

I might be helpful if you were to refresh us on what valve train you are using on your EQ heads. I've got EQ heads here that don't run the stock Magnum parts. Are you planning on swapping the valves also?

You can get both flavors, at least in the Performer line.
Edelbrock Performer RPM Chrysler Magnum Cylinder Heads 61775

Edelbrocks have a Magnum and LA gear running head and that would be the only currently produced head that is equal to or better than the EQ head in the replacement/street performance arena in a OOTB state.
If your looking for a OOTB cylinder head that out performs the lightly worked EQ heads, your not going to find it unless your stepping up to the Victor head or a already modified cylinder head like a pre ported head. The only pre ported aluminum cylinder head I know of from the manufacturer is a Brodix head.
Not knowing your heads flow rates is a slight problem. But! As mentioned, the Trick Flow heads have good reported port flow but they are not yet available to purchase.

My EQs have 2.02 +.050 8mm valves, springs, locks , retainers, all picked out by Brian at IMM to match the cam. The work done was bowl porting to match the new 2.02 valves, flow came out to 272 at .600, pretty consistent with the numbers for these EQs off other benches. The current heads dyno'd very well, work very well with the airgap making 504 hp on a 408 pump gas motor. So I don't want to sacrifice much if any port velocity, since my converter stalls less than the torque peak by about 500 rpm. My main reason for considering the swap is weight off the front of my Dart. Not a whole lot of traction below 40 mph or so. I figure with moving the battery to the rear and going aluminum heads I can significantly change the front/rear weight ratio. Add stickier tires, and it ought to do much better. I still have a steel hood but have coilover /rack and pinion front for weight savings up front.
Keep yours...

We'll be working with a company close by, to do a partial cnc 280cfm head OOTB in aluminum, ready to go for around 2K. Will be the end of the year though...
That is a very nice number to peak at. Lots of power should be ablethrough that. Not that Greg has a slouch by any means.
For LA or Magnum?

If it's all about weight you can experiment other ways to figure out how much it will actually help... I'd relocated the battery and put on stickier tires first and see how it improves. You'd also lose roughly the same weight for a lot less cost and hassle by swapping that steel hood for a fiberglass one. Personally I wouldn't go through the trouble of swapping to aluminum heads if I already have good-flowing iron ones unless they're the "next level" in power potential, like the Eddy Victors or other big-port competition AL heads.
I plan on keeping the hood , so if i want weight reduction up front i have limited options. I was hoping there would be some cheaper versions available bare. Ebroc k s are 1560 a pair bare, not worth it for what i am wanting to do. I agree on the stickier tires. I could at some point mini tube it, since i have already moved in the springs.
Chassis FIRST ! BEST BANG ,FOR THE BUCK!!!!!!!!!!!

Keeping the hood? why
get some glass fenders and bumper
al radiator
core support
go light or go home
We were amazed on how much the "don't touch it's aluminum" front end made on the 413 nothings changed in 56 years

Greg, is this anDedicated race car?

LA...unfortunately the Magnum design is a dead horse other than the iron heads and the Eddy head. The eddy head is a good design, however the price of the castings is just too high. I'm hoping to do a head and head bolt kit for around 2095.00 out the door.
No, this is a show/cruiser mainly, with fresh $8000 paint. Thats why the steel stays.
Hmmmm, a fitting tapped into the heads and internal line for oil to the LA rockers might interest some guys in my boat,,,,,,,,,, (magnum block) as an option of course for a few more $$.
Thanks, it was wyrm’s comment below
that had me wondering. I generally hate that statement unless it is applied to a Dedicated race car. And even then sometimes it makes me wonder if other people think you’re made out of money and can just throw bags of money at the (perceived) problem like the US government does, throwing money at there problems.
(Real or not)
No problem. guys want to help,,,,
