What cam should I get?

OK I understand now that I should use an oil that has anit-wear additives for my flat tappet cam. Now I have recently changed the oil using Valoline 10w-40 and was wondering what should I do now. I am going to change the oil and filter when I have put 1000 miles on the motor since I changed the oil to get rid of the moly based cam lube. Now should I immediately change the oil to a racing oil or Rotela 15w-40 or just hold out until I get to the 1000 mile mark for now. Or should I throw in something just to make it to the 1000 mile mark. I am concerned now that I have made a mistake on the oil I chose and don't want to harm my new cam. I think I will eventually just run the racing oil but not 100% sure of that either. I have just got done reading on Hot Rod that the racing oil is better than the Rotela T and in 2007 Rotela is not going to have as much of the anti-wear additives because the big rigs are going with cataylic convertors. That's what they said any how. What do you think I should do at this point?
