I think the S1X cam from intense is right up your alley. Great cam for stock heads. Personally i'm going to run the xp cam but i'm using nitrous to take advantage of the exhaust duration on it. There's also the NIC from ZZP which is a crazy cam for non-i/c'd cars but it's really aggressive and not the best daily driver cam, not to mention you need a really experienced 3800 tuner to get it running correctly. That's just a little info i can throw your way.
