Square port heads. Not much more to say...it is an LS6.

The swap with a nice LSX is a great idea and I will have to think about it since the LS6 motors have a huge appeal. I kind of like having the only LS6 powered truck around though. You won't find a true LS6 every day let alone in one of our trucks. I plan to occassionally show the truck so it may get quite a bit of attention once complete. The motor only has about 15,000 miles on it so it should last a pretty long time.
