I have a 1968 Cadillac Coupe DeVille with a 472 Engine. Im trying to eliminate the Smog pump and the hoses/tubes that go with it. Taking the pump off is no problem, but my question is this... The smog pump pumps air into tubes that connect to the heads (one for each) Does anyone know if i can just take the tubes out and plug the head.. or do i need to swap the heads? Im not looking to make this a race engine.. just a solid daily driver. Any help would be greatly appreciated.
