Headers Question

Got a pacesetter header that was supposed to go on a pre 91 258 engine with a 4.0 head. Will it fit on my 98 4.0 head or are they completely different head measurements?
Thanks
 
All the 4.0 heads use the same intake/exhaust bolt pattern and the exhaust ports (tho different sixe) all seem to fit in the ex gasket so the short answer is the header will bolt up - but newer XJ's use 2 O2 sensors so you might need to add a bung?
