Default h/c dilemma... details inside

Well, I just recently purchased a h/c setup. I am in the process of still trying to choose a cam that I want. The heads that I bought are LS6 style heads, stage 2. Does this mean they are a 6.0l head? I chose the option of 59cc. Now, I was told that these heads were 11.1:1 compression without having to mill them. How is this possible of getting that compression without having to mill? Also, since they aren't milled, I am going with a custom cam of 230/236 .592/.602 on a 112. I DO NOT want to noth my pistons.

Anyone care to chime in?

BTW, these are PP LS6 style that are hand finished. So are they a 6.0L head and just welded up?

I am under the impression and was told that I would not have to notch b/c they are not milled. But I ask again. How do you get 11:1 and not mill?

yes they start life as a 6.0L head, the chambers are welded up and then CNC'd to 59cc's so no milling is involved. the heads will have a stock height of 7.450". Brad or I will sit down and redo all of the numbers but off the top of my head I can't see why you would need to flycut. What size valves did you order? 2.02/1.60 or 2.055/1.60?
