Everything is TTY...except for the side bolts in the mains...just be sure you keep the same bolts with the same main.
Clevite77 Main/Cam/Rod Bearings...or OEM replacements from your local auto parts store. You WANT new rings...new everything IMO...your in there...don't skimp man, trust me. You can still do it on the cheaper side too if you do it right. I used Hastings Rings...and you want to gap them 90* apart from each other...if you line them up...you get blow by...and it'll burn oil...not what you want. Just be sure to put a good chunk of assembly lube on EACH and EVERY bearing where the crank journals touch on the mains...THEN, lube the rod bearings after you set them in the rod cap and connecting rod itself...don't be afraid to use a ton of it...it never hurts to have too much lube LOL
