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.
