does any one have this setup runing now,last night i switched the oe cast iron intake on my v-code super bee with an a-12 alum six pack intake to lighten it up. while the paint was dring, was thinking it would be cool with alum heads with stock manifolds. mocked up a manifold set to eddy rpm angle plug heads in the shop, driver side looks like it would work perfect, pass side is only close on #8,#6 plug to dump might grind pass manifold a bit? want to keep the manifolds on it,car is all oe except for wheels and radio

well if a guy on here made 570 hp on a low deck,with eddys and manifolds how much can you be losing 40hp over headers it wont be much. i want to retain the stock look, not a race car, show car. im sure it will run better than tired, heavy 906s

I'm guessing that is a heavily modified enigine. And the Main's were "hogged" out some. I don't think they up-grade on a stockish 440-6 would be the same. You'd probably add more HP by getting a set of headers.

I remember Andy's 440 buildup w 68-70 HP ex manifolds & 3" exhaust that netted 550 hp w alum heads. Dont recall if it was a stroker or the brand of the alum heads.

That seems in the ballpark. You'll just have to try it and then go from there. I had a bunch of 475 rwhp pulls with that low deck 470 motor on the chassis dyno but that was about the limit.
Better head porting and more intake rocker ratio would have been the next items for me to try. If you're shooting for 500 rwhp you'll probably need to thrash the combination a bit. I'd suggest 1.6 or 1.7 rocker arms on the intake and 1.5 on the exhaust as one area to test.
Have the heads been modified? The CNC porting from Modern is a pretty good package. I think you'll need some good port work to hit your 500 rwhp goal.
I'd be very surprised if the 6 pack intake would support 500 rwhp, it really isn't a very good intake. Guess you'll find out. If you do back to back testing with the 6 pack vs. a Performer RPM I think you'll find some gains.

It was a 470" engine , nothing real exotic in the build, flat tappet cam, the manifolds were AS CAST ...
so you think a pair of headers is going to gain as much as changing from a set of heads that flow maybe 220 at .500 to a pair of heads that flow 280 plus at .500 ???

I think there are easier and cheaper ways to get HP than bolting on a set of Eddy heads. Especially if you are going to choke them up w/ a set of exhaust Mani's. Why not run the stock 2.25 exhaust while you're at it?

Yes there are , but the person wants to use the parts he has , just like you want to use 440's and put holleys on them with headers ...it's all about CHOICE .

I thought he wanted to BUY the heads and install them? Does he have the heads sitting on the shelf? Totally different thing...and I put 3 holleys on my lastest ride.

ok lets go back to sqaure one the confines of the the build: 1970 v-code all oe 440+6 4spd 410 dana show car with only 2 mods on car. motor bay must look all stock from stock oil pan,stock 6bbl intake,stock manifolds,stock rad/fan anything between these parts is all fair game.. ie stroker kit,solid cam,alum heads ect..no headers,no aftermarket intakes. love to hear any combos on big blocks wedges with alum heads with manifolds

Then you can't use edy heads. They look nothing like the stock units. If you want the stock look the "stealth" heads are your only choice.

The six pack intake is probably the best factory intake to use for that type of build. Should be a fun combo.
The 500 rwhp is going to be tough to hit though. An easier target to hit would be 500 ft-lbs of torque. My low deck 470 with the AVS carb, RPM intake, Eddy heads and HP manifolds would lay down 530 ft-lbs of torque at 4300 rpm.
I wonder what HP ed cook is making , he is knocking on 10's with his 6pk , but I don't know what's been done to the intake , if anything , he is also using iron exh manifolds .
hemi , what class is allowing you to use alum heads ? is this a SHOW class , or racing ?
