Hi!
The bearings need to be replaced if you are serious about you engine! -They look terrible!
See to that you get C3 or C4 ball bearings ,those have more play than standard bearings, which means the engine has less friction and has the ability to turn more rpm.
Swiss brand WIB is regarded as being one of the best manufacturer.
