440 Engine Knock

What I am thinking
> Turn engine up side down on the engine stand
> Check Crank end play
> Check rod axial play
Then
> Remove the Rod bearing caps and look for wear pattern
> Remove Main Caps and check for wear pattern
Question
Should I remove the bearings , rods, caps, and check with plastigage ?
If I do remove the bearings can i reinstall them or do i need New?
I am thinking if a bearing has any issue I will see it in the wear pattern ?
