Here is how the head looks after the pads have been machined down and the new holes drilled and tapped for the hold down screws. The Jesel stand uses seven 7/16-14 bolts to hold it down rather than the five 3/8-16 bolts for the factory setup.

It is a little tricky re-drilling the end holes for the larger 7/16 screws since the proper tap drill is smaller than 3/8ths. So basically a small amount of the existing threads are left in the hole and you then have to retap thru that. It cleans up okay but if you're going to run the Jesel setup you should really buy the heads setup that way in the beginning.
