Mad-Great work I love your threads and work ethic,I have a rookie question about the vac. pump,Are you pulling from both valve covers???? I have never used one but I'm intrigued to learn more about them.Just thinking to balance the pull of the pump you would suck from both sides equally and hence balance the seal of the rings again not dissing you just asking for more knowledge of how those vacuum pumps work--Thanks Steve
