I traded all of my Edelbrock 1406 problems for Holley 650 DP problems.
There you go.
Hardly. I've had ZERO problems with my Holley. Why? I run two fuel filters. I fought and fought and fought to avoid swapping to a Holley. My former co-worker kept telling me to do it. When I finally did, I gained a TON of throttle response, gobs of torque and HP which translated into .22 and 4 MPH in the 1/4 mile with no other changes.
Your next thought is probably going to be "Yeah, but you lost mileage." Nope. Gets the same exact mileage.
I've since gotten a friend to swap out his Carter for a Holley on his 340. It's like a different car. He loves the power.
Also, the old wives tale about the power valve blowing out only applies to ancient Holleys. All new ones have check valves that prevent that.
I been running Edelbrocks for years, my 750 since 1988. The 600 since 97, zero problems and I bet it get's way hotter here, zero heat soak issues. If you are having a loss of power you ain't tuning it right. In one of the recent Car Craft's they had a big shoot out comparing carbs, the information is interesting, read it.
So, making a long story short, what were the shoot out results from Car Craft?

Not much of a difference between the carbs once they did a basic tune (jets and maybe power valves). Out of the box there was a larger variance. The edelbrocks were leaner at cruise than the Holleys, but booster design varied the Holley's. So many variables that could be tweaked with a more serious tune (air bleeds, booster types, etc). Basically, it boiled down to this, not enough difference to make a recommendation based on the observed data. http://www.carcraft.com/techarticles/ccrp_1210_seven_budget_carburetors_tested/viewall.html
They say there are no such thing as a stupid question.
They say there is always the exception that proves the rule.
Don't be the exception.

The edlebrock wasn't tuned properly if it was the same CFM rating .

Thanks very much for this info. It proves as I suspected from my past experiences with both the Holley and Edelbrock carbs. There truely is very little difference out of the box and if you want to improve drivability or try to rate one over the other, tuning factors and replacing out of the box components comes in to play. Great article from Car Craft.

I had small problem of fuel boiling in my carb and sometimes after a very hot start it would flood and I would have to keep the pedal on the floor to get it started and then get moving to cool it down some. Its because of the cheap pump gas fuel that they added more ethanal to this year as I have never had this problem until this year and I have run this same basic fuel system for years. Oh and my carb is an 850 DP. I already had a 1/2" phenolic spacer so I added a heat shield below the carb and actually put a cool can back on the car. I only use it it very hot humid weather but I will throw an ice pack in the cool can when I cruise on them very hot days and I have not had the problem at all anymore. And my eng never overheats as it will get up to 190 to 200 tops on even the most brutal hot days. Ron
Thanks Ron. I ordered a heat insulator from Jegs Friday so I'm going to try that first. I put an old .200 phenolic spacer that I had under the Carter and it helped so I'm hoping the .320 spacer kit will take care of it. I've got a Moroso .500 insulator but I'm a little leary about installing that and raising the carb up too high. I've got all that Ramcharger duct work and air cleaner. If the .320 insulator doesn't help, I may go head and block the crossovers. What seems odd to me is that the Edelbrock and Carter is basically the same carbs and I didn't really see this with my old Carter Comp on it.
I bet you the reason the eddie carb run hotter and boils the fuel is because it's leaner than your old carter.
The 1406 is lean from the factory, use the jetting chart from the 1405 and richen it up.
Been tuning the 1405 since the 90s and have changed mine and driven it all over the country from Key West and sea level to Pikes Pike at 14110'.
My manifold with no heat risers, I have driven this car in Reno and Vegas in July and Aug and to the top of Pikes Pike on a 95 degree day. That's huge, please go try it someday.

I'll try that. You happen to have the 1405 chart handy? That 1406 does seem a little doggie at part throttle. Probably the reason.
Been looking for a better picture of the tunning chart for a 1405 and have not found one yet. I keep looking or see if I can get a better picture if someone else don't post it.
Here's the car in San Francisco facing the Pacific ocean. It got a good salt spray from the ocean within a few hours, this RV park allowed you to use as much water as you want to wash your RV. Some people washed there stuff every morning. 
If you look hard enough you can see Hawaii off to the left. 
Then a day or so later were at 4400 feet, I change the carb all the time and don't leave it the same. 
Like driving on the moon.

I used this and it helped a bunch on my Thunder AVS.
I also have an electric fuel pump however, the spacer helped more with vapor locking with 91oct and very hot ambient temps.

the internal spec of the Ebrock has to be different from the carter , the similarity is only on the surface . Don't get to carried away with spacers with your ductwork.
I can't understand why you haven't put the rebuilt carter back on , or would that be too easy ?

I got that 9266 spacer but when I saw it the material made me question if it would stand up to the stock manifold heat crossover. I should have read the instructions before buying it appears. It's not recommended for stock manifolds like mine. To use that, I'll need to block the crossovers.
Where did you read this? I didn't see it. We are not talking those POS cool carb spacers. Nylon can handle ther heat.

It's in the instructions for the 9266 spacer.
Wow the listing says extreme under hood temps, That's kind of BS. Then just get a good ole old fashion phonelic spacer, they work fine.
But If you having trouble with this, then I change the manifold to something without a heat riser or block yours before going any farther. My
