They call for .0045"-.0055" clearance. I originally set them up at .0045", It's been lightly honed now twice so it is now around .0047"-.0048" I can guarantee it's not piston slap. It would need .006"-.007" before you would really start to hear anything loud. Piston skirts still measured really good this last go round.
