Stop in for a cup of coffee

So after being left on the roadside in the Demon on Sunday fiasco...I changed to a 750 Holley vacuum secondary carb from my son's rat rod for the short term. It ran pretty well, didn't die at all but still has quite a stumble under load off idle. Seems like an accelerator pump issue/adjustment/cc issue. Bogged when attempting a burn out and a stumble if just idling and a sharp wide open throttle stab. It made the whole trip that it didn't make on Sunday and transision driving down the road was really good. I can't believe how hot the hood and fender tops get from the fenderwell headers. Almost too hot to touch. There is no insulation on the hood but maybe there should be? As for the fenders, with no inner fenders, I thought there would be enough air flow to keep them cool but no way. Header wrap or ???? thoughts??
