Crank bearings good or bad
Bryanj:
That damage has been caused by somebody being hamfisted it getting a cotter pin out that locks the rocker shaft.
That is the big problem as the shaft cam move in and out now , it probably would not leak but i wouldnt run it.
Any 500/550 rocker cover will fit but only the late 76 onwards have the locked shafts, i am told that earlier ones can wear the cover holes oval but i have yet to see one, you can sort of lock the early shafts by putting an O ring in the end bore before fitting the end cap
Murf:
BTW your crank journals look really good, hope mine are that good when I pull the bottom end apart.

Do you need to lock the shafts in place and will my current breather cover fit

I agree with Murf it certainly looks as though you just need to fit the right colour shells.
Have you managed to find any paint remnants at all Acro?
Bryanj:
If the end was not broken out allowing the shaft to move inwards too far it would be ok but as it is i would say not
