The reason PES's do not pass through the lump is Poor Quality in the casting. If you could look at a set of PES's you would see the shift/off set in the casting,So the bolts do not fit.When the boss has been Milled!! out the right way!!!! There should be very little to NO boss left behind. Then you blend off the rest of it. Then you can Respot face off the floor.Once the cutter has made a full circle cut you are done. The is no Need to counter sink the New allen head bolt.
So when installing a set of PES lumps you can either Open the hole up before hand Or after they have been bolted in. Either way
just be sure you have clearance around the Head bolt before you
do the final install.
God doesn't like ugly.
