I'd go heads and cam, I also love the lope you get with a good cam.
FI will stress the bottom end more and I would be esp. concerned about bearings at that point. As far as those with SC's now, if you've had your motor apart have you noticed any abnormal wear on the #1 main bearing. I remember in the old days, 5.0's, the guy's that ran a centrifugal blower had problems with the #1 upper main bearing due to the extra stress the blower belt's tension caused.
