Insulating Against Heat on the Carb

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.

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.
