I've got an 84' 350. The previous owner, or original owner, put an edelbrock carb on and blocked the EGR valve. They also removed the solenoid and a few other items along the way. Anyways I've replaced the edelbrock carb with a holley and want to upgrade the manifold to an edelbrock performer. Should I forgo buying one with an EGR and just get one w/o the EGR?
