Re: 1967 Camaro 327 L30 4 Speed Adding Headers
If it was me, I would change out the exhaust and keep the manifolds. With the headers it's not only the steering box, but clutch linkage, melting spark plug boots and speedo cable, plus the alternator mounting. I had no choice with mine, I bought the car with headers, I am considering changing mine back to stock manifolds. I doubt you would notice any performance gains, moving to headers.
