Funny enough, I read an article a while back where they actually measured blowby with a variety of gaps and found it all to be about the same from 19-28 thou.

for street, lower hp I would go .005per inch bore, full out race .0055 per bore and what ever you make the top at least the same on the second ring if not .001-.002 bigger, never had any problems that way.
theirs a saying if you build to tight everybody will know,(BOOM) you build loose your the only one that knows.
