So, How can a 4-bearing SC cam fit into the 2.7 liter 3-bearing cam towers?

The lobes on the 3 bearing cams are welded and reground to match the profile of the 4 bearing SC cams. This is a good option for the 2.7s because Porsche seemed to get the CIS cam profile optimized by the end of the SC era. I really noticed a nice improvement.
