EFI exhaust manifolds?

Has anyone got a donor for cast EFI exhaust manifolds? Looking for cast manifolds that have the o2 sensor port and will fit the EB frame/ Auto trans.
It looks like 95ish F150 manifolds would work, but I'd rather know if someone has already worked out a good donor.
Thanks
Tom

I used the manifolds off the 88 cougar motor I pun in. passengers side is a bit tight but nothing a good exhaust can't work out.
