Dual plane all the way. I made the same mistake almost 10 years ago.
Roadrunner, mild (emphasis on mild) 440 with a torque cam. Cast iron intake, exhaust manifolds, and a holley dp carb.
I switched to a 750 edlebrock (sold the holley) and when to a Mopar M1 single plane high rise manifold.
It never ran the same again. No low end torque, killed drivability. My embarassing 15 second quarter mile decreased to an even more embarassing 17. It was quite a learning experience. Go with a dual plane.

I think I can say that pretty much without question: The Edelbrock Performer RPM is going to be your best option. Its a high-rise dual plane that works real good on stock to mild street / strip motors. Only issue might be hood clearance (???).

Some basic aftermarket dual plane manifolds are basically the same as your cast iron intake, only lighter aluminum. Edelbrock performer or performer RPM (this sits slightly higher than stock) would be my vote for a stock motor. Or just my  , since there won't much be a noticeable difference. Just put a 4 hole spacer between your iron intake and the carb for some added throttle response and some power gain?  anyway you go, good luck. SP would be a step in the wrong direcetion though. eight

the single plane Holley Street Dominator was the BEST dual plane intake ever made

Look on ebay and the classifieds here for a used edelbrock DP4B intake. For stock heads it's all the flow you need. You won't gain anything except less hood clearance if you go with the performer rpm over the dp4b.

The holley SD is a good intake, but not for a stock 383 with 3.23 gears.
whatever you say..

Agreed, but we have all been through this, haven't we??? First its an intake. Next He'll look to buy a Holley carb. Then he might as well add headers. Hey, next let's take a stab at a Cam-swap. Then, how about some deeper gears.... I can't be the only one that's been through this!
So with that in mind, The RPM is an intake that will support his desires all the way up to and including an 11-second stroker motor. Since it also works well on stock-ish motors, might as well go straight there, now.

True, however for as long as he's running bone stock heads, he will never see a noticable increase in power with the rpm over the dp4b. Heads are the bottle neck at that point. The 383 intake shootout hot rod mag did showed exactly that, I think the dp4b even put out a few more ft-lbs(and at a lower rpm) than the rpm when tested on a stock headed 383 with a decent cam. I think the rpm was good for 5hp or something insignificantly like that. I suggest the dp4b because he can bolt it on and go, no issues with needing drop base air cleaners is a plus.

What makes you think it's a heat related problem?
when I start it cold it starts up fine and when I have a quick stop to make (10 min or so) the engine seems to take alot of cranking to start back up....(eng temp seems alittle high, plus enging compartment feels hot) and alot of the times I'll open the hood and take off the air filter to get it to resart because I don't want to wind down the battery

No need to ch manifolds. Lets see if we can solve it as is. heat riser sending heat up top?. Need a thin gasket on either side of the 1/2 black plastic phenolic spacer? E10 gas (ethanol) by chance. the eddy 750 may have an issue  . Something besides the cast iron is causing the prob & if it is not heat related check for a good blue spark when hot

"E10 gas (ethanol) by chance"
... YES... every grade has 10% ethanol around here.......... I remember the days you could get leaded regular gas  would that be the issue........... besides the restart the motor has been running great........

When E10 became an option at the pumps here in Nebraska in the early 80's it caused quite a bit of vapor locking and stalling at stoplights in the summertime but then later w the intro of fuel injection and carbs becoming nearly extinct it became a non issue. Some eng setups are much more susceptible than others and the ones that are it is severe and a real pain. Any way you could get the E10 all the way out & toss in several gallons of non alcohol fuel of some kind (maybe some racing gas ) to confirm or deny that that is the prob. Changing the intake is not the solution imnho

took the ride for a quick cruz (15 min) and parked in the garage ... opened the hood and noticed the gas boiling in the fuel filter  (clear plastic filter).Filter is placed a approx 2 in above valve cover touching nothing . Temp during the ride was around 180.... so what is a good fuel line to buy to keep the heat out of the fuel line?? braided hose??

what make and model is the best aluminum DP...
Thanks Gents!!
)so I was thinking an aluminum manifold would conduct less heat to the carb... when I'm shutting the car off the temp is around 170 to 190 max so the car is not running hot.... I also have a spacer (1/2.. 4 hole phenalic)on it now. (edel 750) 
).... they had regular leaded pump gas at every station and NEVER had a heating issue.
