Default Stage 2x?

On the MMS stage 2 heads, is the 'x' higher compression option a set number? And if so, what does it step the stock CR up to? Also, how are their valve springs at handling T1-range lifts?
And one more question <img src="images/icons/grin.gif" border="0"> , how do they seem to be working with moderate n2o shots, specifically TNT 75-100?
