Rings??? I'm staring at the pistons and scratching my head if I should pull them out and re-ring them? The top of the cylinders have a slight ridge that I can feel with a fingernail. (Was not planning on having the block machined due to cost)
When running the motor used a little and leaked a little oil, only smoked for a second on start up. Had good power. The heads are already removed (cuz I'm an idiot) so I missed the opportunity for compression testing.
I kinda want to leave the rings alone.
What say the forum???

That engine should be pulled completely down and cleaned at least. There is probably metal from the bearing failure that got pulled back into the oil pump and some usually finds it's way into the oil galleys.
Oil smoke on startup is usually valve guide seals.
