there is nothing wrong with King bearings, we use them all the time (as well as Clevite77's) in our race engines. as far as rings DO NOT use OEM Honda rings. if your honing the block your clearences will go away and the OEM rings will not fit. you will need a set of aftermarket file fit rings, such as Top Seal, Mahle, or JE rings. also balancing isn't needed on an inline engine, there stress loads are always in the opposite direction of each other so they don't cause vibration unless they are WAY out. you can still have a "good" shop spin it up with weights and see if it's out any. and i mean a good shop. we fix other peoples work all day because of shotty machine work.

if this is something your going to beat on do not go OEM. aftermarket companies are out there for a reason.

also if your going NA and the engine will be apart then go ahead and get the head surfaced and get a valve job done. and look into getting a good set of cams and dual springs.

also make sure you replace the oil pump, water pump, and head bolts.
