Gasket between Qjet and intake
Short answer: There’s a thin metal gasket (a sheet-metal plate with four holes) that goes between the Quadrajet base and the intake, covering a heat passage in front of where the carb sits. Missing it causes leaks and a miss. It’s about $5 at a speed shop, and it’s needed on both 1967 and 1968 Q-jet intakes.
