Ok, my 90 XJ's 4.0 is pretty shot, lots of bearing noise and blowby. I have a 258 from a '76 J10 that ran great when it was pulled. I would like to swap the head over to the 258 for a really cheap swap, but I've heard conflicting statements about it. Some say it'll bolt right up, others say water jackets won't line up correctly. I am more than wiling to search this, but when I type "258 block and 4.0 head" the 258 and 4.0 are too short to yeild any results. How can I effectively search this out here to get the answers I need?
