I love my CC306 setup.... deffiantely go that route.. although having a blower is pretty cool. how many miles do you have on your car? I know that having a blower is hard on the stock bottom end, but doesn't require you to tear the motor apart. If you get your heads ported, MAKE SURE to go somewhere that they know what they are doing... I had to tear my heads off 3 times because the place I got my heads ported at didn't account for the increased lift on my cam. But, LT4 heads are deffinately better flowing heads even if you don't port them, but I would stay away from the LT4 hotcam. I agree that 425 is quite optomistic for that small of a cam. but that package isn't bad since it includes the rockers and such.. one other thing to keep in mind, an LT4 intake is only a powder coated port matched LT1 intake, so don't bother spending the money, just have yours ported. honestly, I think you'd be very happy with ported heads, 1.6 rockers and a CC306 cam.... another good thing, the 306 cam is N2O friendly If you want to discuss it further, hit me up on IM or something, I'd be more than happy to discuss with you about it.
