Advice on which heads to use. 360 , 302???

Yeah, I guess I will stick with the 302's and replace the springs.. Thats the way I was going in the first place, when my buddy mentioned his heads.. I tried telling him that I though they would be overkill, but he said with the 480 cam, 3.91 sg , and my 3000-3500 stall, it would be ok. I just hope that cam is not going to be too much.. But I guess we will wait and see.. Thanks to all with the advice and Hopefully by this weekend, I will be ready to install it into the car... Then its on to mounting my shifter and getting everything wired...!!!! can hardly wait!!!! Thanks again.. Matt
