ls1 heads vs. stock 5.3 heads

So your saying that the 5.3's have small valves. I thought they had 2.00/1.55's, I thought it was just the 4.8's that had small valves.

I think they have the 1.890 intake and 1.55 exhaust. 4.8/ 5.3.
6.0L , LS1, and I think the LS2 have the 2.0 intake and 1.55 Exhaust. If I am wrong someone please correct me so I will know in the future.
