headers on 170 /6

Is anyone here running header's on a early A with a 170 /6.
I have been told that there is know header that will install on a 63 valiant 170 /6,, What is the big deal about a 170 /6 in a 63 valiant that I cant do a simple instal without mods to a car I don't wont to cut up or change something to this little car. All I want is to get the cast iron out and keep it stock with a Offy 4bl intake to a y pipe to one good muffler.
about a 390 cfm carb. does anyone here run a 170 with headers in a early A body? I just want to open my hood and see a nice look.
I will be cleaning up the head only.
