I have one of those integrated head engines. I was planning on kepting mine since it runs good enough for me. I am adding Hooker headers and high flow exhaust (3 in). I was wondering about the PAIR set up. you knoe the pulse air crap that makes the engine look ugly. Can these be capped off and a old style chrome valve cover used. The truck is now offically 25 years old so it does not require emissions testing anymore. I know I have to kept the catalyic converter to pass safety inspection. I have allready plugged the EGR and truck runs much better with it plugged.
