Hi guys, I just did a 0.8 ohm duel coil on my Helio clone. I noticed that the clone only has airflow on the one side of the cap. If I'm not mistaken the Helio had air holes on either side of the cap about 180 apart. Could any one of the vets verify this for me. I would gladly machine another slot in the vent valve and machine two extra holes, but I want to confirm that there where holes on either side.
