    For nitro it's typically.009" per inch of bore ! .03783" or round up to .038" when it comes to ring end gap I always error to the larger side! I run .040"-.043" on my blown alcohol BBC with a 4.560" bore and see very little if any blow by especially under boost with the gas ported piston it seals up very well!
