RiceEatingWS6

I've done a ton of searching and still very confused.. I have an 02 WS6 with pacesetter lts, catted ypipe, LM exhaust, slp lid.. and the rest stock.. I am wondering what head/cam package to get.. here's what I'm looking to do: I would like a good cam that make good low end and mid range power and is pretty streetable.. I dont mind somewhat rougher idle than stock but I don't want something very choppy.. sees more street than track.. I've heard a 224 or 228 cam would be good with a 114 LSA..Opinions? Then what heads should I get? At some point in the future I would like to add a supercharger so it would be nice if I didn't have to repurchase these items all over again... Which head do the 02 WS6's have? Should I just have them ported and how much does that cost? Your advice is much appreciated...
