Alright, I've had a set of bassani equal length headers for a while now and just never had time to install them. I've got this weekend off from work and will prolly tackle the install tomorrow. So I've got a couple questions... what is the best way to install equal lenght headers, top or bottom?... bassani's directions have them installing from the top but it seems as though it would be easier to just drop the k member and bolt them up?? anybody have any experience bolting up equal lenghts on a 5.0, any good info for me. what spark plugs does everyone recommend while I'm in there... motorcraft, ngk, autolite???
