I see these at Carlisle every year. I Know he was at the Ford show, I'm guessing he'll be at the Chrysler show also.

Here ya go! Just added it to my wish list at Summit.
Extreme Shield
I'm also running the Edelbrock insulating gasket.
I've cured similar hot carb issues in the past by both making and installing a semi-ridged, sheet-aluminum plate to shield and dissipate heat transfer from the engine to the carb, and installing a 1/2" phenolic spacer on top of that. Using this combination requires 3 gaskets and longer studs. Be sure that the aluminum plate does not interfere with any linkages or throttle blades etc.. Also, depending on your intake design, you can use an open plenum or 4-hole style spacer. I sourced a one foot by one foot piece of aluminum sheeting from my local hardware store and cut it to fit. It was pretty thin, but still thick enough to be somewhat rigid.
Another successful addition I made was to use a gas filter with the return nipple to circulate the fuel back to the tank. I had to add the return line to the back of the car and a fitting on the sending unit to make this happen.
Having your ignition timing properly tuned helps too.
I would not recommend using those thin plates and gaskets that you stack up under the carb base. If you don't run the nuts down evenly, you can crack the ear off the carb mounting base... Been there done that.
Now I only will go with the thick gasket, not the stack of thin gaskets and plates...
So I will revisit my question one more time from previously, is the thinner Edelbrock heat insulator gasket (0.32" or 5/16", whichever) better than a slightly thicker (1/2") wooden or phenolic spacer? I see a lot of good ideas, but didn't really get an answer to this question. I appreciate all of the input to this discussion.
Yes, I have. The insulating spacers address the conducted heat only. The large plate type insulator that I've suggested several times address' the heat radiated off the engine below the carb. A spacer won't do a lot for the radiated heat, and a plate can only do so much for the conducted heat (acts as a heat sink). A combo of both is the best route forward. Plate on the intake, then the spacer.Another thing that we haven't addressed is what about the make up of the fuel is causing it to evaporate out of the bowls. At least around here, it is made up of 10% ethanol. If I run the expensive premium with NO ethanol, the situation improves.
Yes, I have.
wow what a difference a wood 1 inch spacer makes!!!!!!!
I have 12 inch aluminum spacers and nether one of my edelbrocks gets in the ballpark of hot ! lol
triple-R in post #25 I think you're talking about a composite material like what the Milodon oil pan gasket is made out of?

What did you end up going with? I just bought the Edelbrock thick gasket https://www.summitracing.com/parts/edl-9266 and will be getting it running hopefully tonight. I also am going to use header wrap around my fuel line above the intake manifold leading up to the carb. We'll see how it goes. Thing all but died off the line against a Monte Carlo a couple weeks back and I don't like to misrepresent Mopar.
