Just called Rev Perf.
I called based on their website that wasn't clear as to whether the cases on a 110 need to be bored to fit the 117" cylinders.
Here is what their website showed.

I called the 1-866 number above.
Talked with "Andrew", he said the 117" cylinders did require case boring to work on a 110.
Not sure whether "Andrew" was the owner or the floorsweeper but he seemed somewhat knowledgeable.
All I can say is DAMN, so much for that idea.
