You need to document the rpm when installed both ways?

I doubt it making a noticeable difference for when the reed valves are open, the piston is headed up and the intake charge is not going up the intake transfer passages.

The intake charge moves up the intake transfer passages when the piston is headed down and the reeds are closed.
