intake is 1.89" and exhaust is about 1.55" I think. LS1 and 6.0 use 2" intake and 1.6" exhaust I think.
I'm still not sold on putting stock 5.3 heads on a 6.0 with just bigger valves. GM developed the 317s for a reason. They flow more and will make more power. The only reason I can see putting on 5.3s is for cost since you can get them almost for free.
