Yes it will raise the compression. How much depends on how much you are milling. If you are just cleaning up the deck surface with a .002-.003" mill, it won't change the compression enough to worry about it. Let me know if you are milling more and how much and we can calculate the compression change for you. Remember you are already raising the compression putting the LS6 heads on since they are 2-3cc smaller than the LS1 heads. Your compression should be at 10.5:1 with the LS6 heads before milling.
