Great header, mislead name
While looking closely at the pictures of these headers, I noticed an air tube on the passenger side header. The title is 5.8L without air. I chatted and was told to block it off. Once I received them, that wasn't really an option. Luckily I have a local welding shop that removed the tube and patched the primary fairly easily. They bolt right up though. I am installing custom exhaust, so I can't speak about that, but you must find a new way to secure the oil dipstick tube.
