Re: 1962 Headers

It's not a good idea over long periods because cold air on hot exhaust valves can cause warpage, (the same reason the old Hollywood Wolf Whistles were so hard on engines). I did drive my 350 V8 5 miles to the muffler shop with nothing but ram horn manifolds, and it suffered no detectable injury.
