4.5hrs on the 1st IH and they are pretty much done......36mm at the top, moved to 35 at the boss, and narrows to 33mm at the IH to head surface.

Bosses are gone.

2ndries are at 36mm

I am interested to see the performance difference if any, its amazing how much time it takes to open up the area after the boss and the IH to head surface in comparison.(meaning going to a few mm/36 takes forever in comparison)
