the 6.0 heads wont work right on your setup...and youll need to port the 5.3s....its advised that youll need to do a little more to them if your going to run that 150 shot, because of the crompression increase their going to give you....a good set of ls6 heads ported would be good...

I've been told to go with the LS6 heads for my future build-up because the "D" style exhaust ports flow better than the "oval" style exhaust ports on the 5.3L castings.
