So you’ve bought a full gasket kit and plan on opening the engine, as others have said you might as well measure inspect but plan to replace all the main bearings and con rod bearings.
New cam chain, primary chain, tensioners for chains, Seal kits, dowel pins sometimes they get stuck in the cases, new chain and sprockets, plan on replacing some of the hardware like any countersunk screws if they’re tough coming out and the heads look manky. Fresh clutch, measure clutch springs replace if necessary.
Fresh rubber intakes for the carbs, if yours are old and hard.
Those are some of the things I’ve had to do in the process of my 750 engine builds. I know some are engine adjacent like fresh chain and sprockets but usually when engine is out it’s time to give the bike a solid going over.
Heck I’m down to bare frame on this engine rebuild…

Well, entire cam chain system and seals and also the intake rubbers were supplied along with gaskets from the start. I asked about the primary and got told it wasn't bad. A new piston ring was needed, the pistons were cleaned up too. Also a stripped thread in the cylinder head was dealt with. I've been a bit lucky I think. ;D
Bryanj:
Disagree about shells, inspect yes but replace only if wor and make sure you know where they were originaly
