Head Choice

So I've been thinking about doing a blown 390 stroker one of these days, but I'm not sure what heads to go with. It's going to be quite some time before I have the money to do it all, but if I had a good game plan I could try to find some parts on discount or maybe used if they are in good shape, but I'm not sure what to look for. I'd like to go aluminum at least to keep weight down and preferably not something thats going to need a lot of porting (I don't think machine shops around here are the most reasonably priced and I don't have the guts to do it myself). I figure I could drop heads on the engine now and then save up the money and do the blower and stroker kit later. Any suggestions?
