Quick S&P motor mount question

[NvrDun71]

Those that are running S&P motor mount adapter plates along with energy suspension poly motor mounts are you guys running the secondary plate that is included with the mounts? If so did you have to grind down the hump on the backside of the mount/plate? I am running these along with stainless works headers # CALS1SB. These are the stock placement (no setback) mounts for what its worth. Any help is appreciated.....
