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

Ok, I am in the final stages of putting my motor together and I have run into a fork in the road. I have a 318 std bore - Lunati cam .480/.480 and I can either run my 302 heads I was planning on running, or my buddy has a set of ported 360 heads assembled with comp springs for 100.00. I have a set of 273 Hipo heads that came off a motor with a crower .521/.528 cam and I was going to pull the springs off those heads and put them in my 302's. But I know the 302s run a rotator and I dont think the 273 did. Can I ever use these on 1990 302 heads?? If not I guess I will just buy the 360's. (360's have a stud that needs fixed, buddy couldnt get headders to seal on it) So I can live with that.. Just getting eager to get this back in the car, and dont want inpatience to mess my engine up.. I was thinking that with that size cam, Maybe I should go with the 360's due to the larger valves and ports.. Any advice or suggestions would be appreciated.. Thanks Matt
