When it’s the perfect clearance, check to see whether the next size up fits. On the flip side, when you have an excessive amount of clearance, the engine will run, but nevertheless, it won’t achieve anything near its performance potential.
What you will wind up doing is measuring every one of the clearances. Some valve clearances are going to be within specification and some might not be.
