I have a 80 Cutlass. I'm building an Olds 350 for it and now I'm looking into dual exhaust for it. I'm thinking of getting a Jegs or Summit Dual kit. Any info on those would be great. I really need help choosing the Headers for it. Long tube or shorty? I've read that some shift linkages may hit? What else is a problem. Which headers will go in with the least problems is what I'm asking. Sorry I'm a Noob
