As with all Holley's, use the non-stick blue gaskets or get the Superformance gaskets to rebuild them. I always block the heat crossover and insulate the fuel supply lines to keep the heat out of the fuel, but I live in a moderate climate too. A wideband sure helps in getting the jetting and accelerator pump shots right.
