Those are not used bearings are they? They only reason I ask is because of the discoloration for the main bearing all the way to the right. But on to your question. They are incorrect. The bearings that are on the outside both are the middle bearing. One goes on the girdle and one in the block. The rest are all the same and just go in the rest of the block and rest of the girdle. The bearing that goes in the middle is your flange bearing and is what keeps the Crank from moving in and out. Hope this helps.

hmm as recently as yesterday i also installed my acl race bearings and from what the repair book said the undulated bearing go on the top, which from your pic i only see 3 of the bearing undulated(correctly placed) and the two on the side are plain(incorrectly placed) from my point of view...

the one guy said to bring the two i have on the outside into the middle (the flange bearing he said)

No the two that are on the outside in the pictures are the flange bearings. They are the only two that are different. They go in the center of the block, with one in the main girdle and one in the block. The rest are the same and go in the other places. Is that easier to understand? Just trying to make sure you dont blow your motor up ten minutes in to run time.
