That depends greatly on what your doing with the engine. For a standard gap theory I run .0045" x bore diameter for the top ring and .0055" x bore diameter for the 2nd ring. And the oil ring should generally be .015".
If you plan on spraying any nitrous through it, you want to open them up a little more to .0055"-.006" x bore diameter for the top and .006"-.0065" for the 2nd..keep the oil ring the same .015"
Hope this will help out
