And I personally don't think chain stretch is as big a deal as you might think. Consider the length of a 4.6L Ford chain from drive sprocket to driven sprocket - - the cam to cam distance on a Cammer ain't so large in comparison.

I degree in the lead cam (driver side), then degree in the trailing cam (passenger side). the newer lobes we've developed with Comp are significantly better from the old stuff and will deliver the same valve action side to side even though the lobes themselves are very different.
