Piston ring gap advice

[Andy_C]

Picking up my glaze busted cylinders this afternoon, and have also got a set of new rings.

Blue manual says ring gaps of 0.2mm - 0.3mm wear limit 0.45mm.

Is this known to be correct, as I want to start putting it all back together over the weekend, and I know that what you read in the Blue Book is not always right.

Thanks.
