I was wondering which brand of headers fits best on a 67 with 327. I know some headers fit better than others and I was needing some help, to get the right fit. The ones I have are old and are in need of replacing. The headers were on the car when I bought it. A couple of the tubes have been creased. What I am looking for is ceramic coated headers. The 327 is mildly built. Any information would be appreciated. Thanks Roger
