I am doing an out of frame overhaul on the DT407 in my 1456. I noticed when I was cleaning the block before assembly that the middle two cam bearings are different. The second bearing from front of engine has two holes that line up with oil passages in block. The third bearing from front of engine has three holes but only two of them line up with oil passages. Could they be swapped or in backwards?

I am doing out of frame overhaul on DT407 in my 1456. Got engine block back from machine shop and noticed when I was cleaning before assembly that the middle two cam bearings don't seem to be in the correct position. The second bearing from front of engine has two holes that line up with oil passages. The third bearing has three holes but only two line up with oil passages. Does anyone that's had one apart have any recommendations
