Max 360 Main Oil Clearance

Am I reading my FSM correct? I'd like to know the specs on allowable oil clearance for main bearings on an LA 360. Under the crankshaft engine specs section, the '73 says: Diametral Clearance Desired: 0.0005"-0.002" and Diametral Clearance Allowed: 0.0025". I've never heard it referred to like like. So, is that the desired and max main bearing clearance for an LA 360?

Also, it looks like rod bearing clearance specs are the same. Is that true?

Thanks!
