I would have the headers ceramic coated no matter if they were long tubes or shorties. Just makes them last longer and looks better. I put a set of JBA headers on my moms 91 LX Vert and I had the ceramic coated and it looks sweet. \
AS far as the clutch cable burning on the long tubes, my little brother has a 79 Mercury Capri with a 306, long tubes and a 5 speed. He has had this setup for almost a year and it is a daily driver and he has not burnt a cable yet. ( NOT saying it doesnt happen, I have done it on my equals, just saying his has not done it.) I am not sure what he what he has done to keep it from happening.
All in all sounds like you are making some headway. I am looking for a beater at the moment so I can park the
stang and start "refreshing" her and giving her a facelift.
Good luck.
Drew
