Small Block & Big Block Chevy Specific - SBC 383 Rings

The rotating mass I bought was fr 11 to 1 compression. They are say for .016 or .16mm on the gap between the rings. any ideas on what it shoud be? more or less? or should I go with what they are saying?

i go .022" on the top and .020" on the second. Don't want to run them to tight. more of a gap is better than not enough. Or you can just take your bore size and multiply it by .004 for a naturally aspirated motor.
