Standard bore size is 92.00mm and standard piston to bore clearance is 0.0015"( 0.03mm)
You will probably find that the skirts of the pistons on cylinders 2 and 4 ( passenger side )
will scuffed/bruised and normally the cause of the piston slap you can hear from cold.
Quite common on the Version 3~4 engines.
