I would like to know how much it costs for a pair of heads to suit v6 superchargedcommodore as my friend’s v6 has crack the in head in her car, I think it’s a VT – VX model.

Unfortunately, we don't have standard replacement heads but we can offer you "CNC Ported Heads" for $1750 postage. These heads would be suitable for your vehicle, for more info please check the link below:
