Piston 0.007 past deck height with 198 rods. Go/No-Go?

Run it. You have an open chamber head. You'll never get appreciable quench anyway. All using the Wiseco piston does in your case is raise the static compression. Measure how deep the chamber is on the opposite side of the head from the spark plug. Add that figure to your head gasket figure. That will be how far the piston will be away from the head.I don't think there's any way in the world you'll ever be close enough to even THINK about the piston hitting the head. I bet the chamber depth is on the order of .100" or more. Add that to "whatever" your head gasket thickness is and you begin to understand my lack of concern.

That said, your static compression will be high with no quench whatsoever. It will be a premium gas motor for sure and for certain. There'll be no escaping that.
