My buddy just got his 98 ls1 block back from the machine shop and they did a hone/hot tank job. The mechanic told him since he honed it, it expanded the cylinder wall slightly and that he should get file fit rings. I was just wondering, what size ring gaps should he be running?? Some guy with a similiar setup told us hes running .018 top and .022 on the second. What exactly should be the file gaps???

There should be instructions when you get the rings. I would follow there recomendation.

Exactly what he said^ also, take into consideration if your friend is planning on using nitrous on the engine because in that case he should gap the rings wider.
