340 Rod questions

I'd polish the journal with 600 wet or dry sandpaper and some WD-40. Then clean it really good.

I do plan on polishing it up.
I got all the pistons out. The journals measure within spec across the face but there is a little taper on them. I apparently can't read because I actually have six 645 rods and two 489. The mirror tricked me or I was seeing what I wanted to see. Three bearings are into the copper like the one in the pic, not wore slap out but a bit uneven. So new bearings are in order before it goes back together.

I also have a broken top ring on #4. Looks like it was cracked most of the way through for a while and let get when released from the bore. Not sure how I will deal with that yet.

Are the tri-metal bearings going to bring anything significant to the party over the bi-metal for a stock-ish build? King or Sealed Power? I'm reconsidering doing the head and cam swap, so these rods won't see a lot of abuse. I'm looking to put the motor back together so I can have the car running while I work on the body. Then it comes out for a full Monty rebuild. It was running pretty well before so should be same with new bearings.
