Sounds like you’ve got the pistons and compression mostly sorted. For the bearings, if they still look fine, I’d send all of them to Calico for their CT-1 dry film coating. Since it sounds like you’re building the engine to last and be trouble free, I’d take the extra step and have the bearings coated. Last I spoke with them, the cost for coating a bearing was like $5 (a no brainer for me with the cases split).
CT-1 Dry Film Lubricant helps reduce friction and abrasive wear. It provides intermittent dry lubrication and is not affected by dust or dirt.
