The ring package is 1/16, 1/16, 3/16. Santelik grinds the gaps to approximately 0.020 for the first ring and 0.022 for the second. He says he would rather the gaps be too loose than too tight. A ring gap that is too loose doesn't really harm you in terms of power. But if the gap is too tight, the ends of the rings can butt together and cause serious damage to the piston and cylinder wall.
