I'd go with the .055....as long as you don't go so large as to weaken the spark (jumping too big of a gap), more gap means more exposure to the air/fuel mixture.

Factory recommended gap for the LS1 cars is .060". Every pack of TR55s I've ever bought have come gapped at .059". After trying a few gaps in the .050-.060" range, I've settled on .055".

I would leave them at the .055 gap. Run the car for a week or 2 and pull a couple to see what they looked like. Mine were running too hot, so I switched to TR6 plugs.
