Comp 262's won't work without Crower offset retainer's. I think that's beyond what the OP is comfortable with doing at this point in time.
For now, to get your feet wet, get some PI cams, they work with the stocks springs and give you a nice bump. Plus after you get in deep enough to do them and become more confortable with working on the car, then you can do springs', retainer's, and aftermarket cams. The best NPI grinds are Crower stage II's, but they require springs as well.
