I think all engines should have steel backed bearings btw ;-).
Originally only the center mains are steel backed as you know and the Mahle bearings I ran have steel center main backed bearings.
Unfortunately, there isn't much choice either. You use what you can get. Only the first main (flywheel thrust) seems damaged and even though I ran 0.015mm (max factory), I think for circuit driving like I did (regularly 7K+) even a little more end play should be considered with the 'new' Mahle brazil bearings.
Everything else seems fine as the filter and the soft first bearing layers seem to have taken in most debris.
Cam looks unused still (Tool steel lifters) and rod journals are super smooth as well still.
Tomorrow crank will be inspected. Barrels have some scorings, but maybe a light hone can help some if they don;t go through the nikasil layer...
