Air Pumps Removed. Now What? - The 1947 - Present Chevrolet & GMC Truck Message Board Network

Truck is an 86 GMC 1-Ton dually w/454.

I have the air pumps and all related vacuum lines, hoses and valves removed. I was not able to remove the air tube fittings from the manifolds. I have the holes plugged right above the check valves for now.

I still have a few things that I am not sure about. They are the deceleration valve, the EGR valve, the control module, and the control relay. I don't know if they will have to stay or not.

Is there anything more I can do without getting inside the engine? At $500 plus, are headers really worthwhile?

Thanks for your help,
Les
