I did the same upgrade last year on my '18 RGS and swapped out to the 2020 HD oil pump. You're good to go! Remember to do a couple autotune sessions to get it dialed in. The high performance oil pump/plates come into play when doing bigger cu in builds, then you need the extra oil supply to keep up.

The HD 8 lobe is working fine in my FM 128 so I’m glad I didn’t spend the money on an S+S setup
