its not the ge journals that's the issue...its the fact your useing journals from another motor....motors all have their own fingure print so to speak...what certain part might work in one block may not work in another without resizeing to match them....so if you use those journals you will most likely need a line hone done so it will mate the new journals and block together so they will be true and round......this is why when you take appart a motor you always number the parts in the order you take them off...even within the same engine parts change size and or mate different so its bad idea to take #1 piston and put it in #6 cylinder and so on....parts could vary within a few thousands of an inch and a few thousandths could mean 200,000 mile motor or a blown motor on startup.
