Wow. Roberto Heras must be licking his chops. And honestly, if he did take EPO, it would have made near-zero sense for him to take it in the last few days of the Vuelta. He had a big lead on Menchov, and didn't need to win the ITT, so the possible payoff diminishes greatly compared to the risk of getting caught.
