Hi Wes and welcome to the forum. I have a '97 F53 and had manifold problems with the 460 and decided to bite the bullet and get the full Banks system and what a difference. I looked around and got a fair deal at about $1800 for the full system, intake, exhaust, etc. A friend and I installed it. But during my research, I did find that Thorley also offered headers for my set-up and it was less expensive but it was not the full system. You might want to check them out.
