is it worth changing intakes?

thanks rusty, kind of what i was thinking,i prefer the clean look, get rid of the egr and air injection.i will also put in valve springs to match the cam. this engine isnt in my duster or demon, its in a79 18 ft. motorhome i just picked up, i trust this site for the experience and input from other members here
Well that clears things up a bit, lol, honestly stock springs would be fine for most any RV oriented cams. But I wouldn't discourage a new set just the same, cheap insurance.
What type of headers? Man, that could kick out a ton of heat right under You in an RV, coated....wrapped?
