I heard to run the thinnest ones when you have advanced the timing.... so that's what I did. Theory is it attempts to put the injector spray back in the piston bowl.

Not sure on the exact thickness but yes I also use one of the thinnest copper washers they make. I don't recall what the service manual states but you can run a much thinner washer without issue.
