89 XJ 94 Exhaust manifold?

Would an exhaust manifold off a 94 XJ fit on my 89? I think that the O2 sensors are in different places though....?
Thanks

The ports on a Renix head and HO head are different. So it won't line up perfectly.

I just got done doing this. The exhaust ports line up perfectly, contrary to popular belief. Only the intake porrts are different on an HO head and they're not too far off. . You will need to have on oxygen sensor bung welded into your exhaust pipe right after the header flange for one thing, and you will lose your EGR, if that matters to you. The intake manifold needs a slight mod done at each lower corner. It will be plain as day and requires a little bit of filing.
