460 Exhaust Leak

Hello,

I own a '94 Minnie Winnie that's on a Ford E350 frame. I have the 460CI gas engine. I have an exhaust leak on the passenger side. From what I've read, this is a common issue with the 460, and Ford did not use manifold gaskets. I've also read that the manifold usually warps and must be replaced.

Has anyone had this issue with their Ford 460?
Where's a good site to buy a replacement exhaust manifold?
Has anyone replaced their exhaust manifolds with headers? How has that affected performance and mileage?

I used this kit on my son's Centarian. That way you can still use a universal Cat on it.

I would use this copper gasket with it too, that way you know there will never be another leak. Not sure which head you have, so I will post both

once installed, you warm up the engine, and re-torque 1 time.

I have also been known to use header gaskets on manifolds...
