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?

Re: Stage 2x? The IIx heads are not a set compression. We normally set them at 11.2:1, but can go as high as 11.5:1
Our springs support up to .600" lift. There is a one year limited warranty on the heads, and an unconditional warranty on the valvesprings.
That means if a spring fails within that year, we'll replace it no questions asked!!
Some don't like the single spring variety, but these are reliable up to 7000rpm. If necessary we can switch to a dual spring setup for an add'l charge.
