    We used to just take an exacto knife, peel open the mold and add two
    small 'v' cuts that create a little channel to move the air away.
    This little channel would only be about .5mm wide and maybe .5 mm
    deep. We would add one or two of these at points farthest away from
    the injection sight. It doesn't take much space to move the air. 

Good luck. Dennis
