Uhmmm.......are you planning on just bolting them on? They require alot of precise machine work. The bearing tabs are on the same side of the block and there is a fair amount of hand fitting involved. If the machine work is complete, then install the caps with the bearing tabs on the same side as the tabs in the block journal. I will assume a machine shop did the fitting/maching and you are assembling the engine. ( I hope anyway) if you bought them and were planning on just bolting them on.........don't......it won't work.
