I don't know what that means.

Parts house only offered one size for main bearings.

..

On the back side of the bearing shells they will be stamped: STD or .010 or .020. The new bearings HAVE to match the old bearings. When you remove the old bearings post some pictures of both the wear side and the back sides if possible.

Measure the crankshaft journals with a micrometer (mic) to make sure they aren't worn, and aren't out of round. This will tell you if the crank needs to be ground undersize, and also tell you what size oversize bearings you will need, if at all.
When you run dirty oil, the babbitt or aluminum face will hold embedded particles up to the saturation point, then they start acting like emery cloth on the crankshaft journals and wearing starts.

Hmmmmmmmmmm. Maybe this is a hint that sometimes learning as you go do it yourselfer may take more time and cost more $$$ than employing a trained expert in that field of expertise.

Sometimes you don't have that option.

Then paying attention studying up and making straightforward response on the thread is called for.

Sorry folks I don't have a lot of time to troll on the forum, I have decided to wait till my buddy can help me before I go any deeper into this creature. My buddy used to be tractor mechanic so he knows what's going on.

I'm glad to hear that. There are a few armchair mechanics here that could steer you in the wrong direction. It should be noted that trolling will bring down the thread, and I don't want that. Good luck with your buddy. Please keep us posted.
