 a bad idea to bypass water from the back of the block to the rad as it
 is needed to warm the intake side of the engine and reduce its tendency to
 go into a mild banana shape.  >>

Paul, I have a hard time understanding this logic, could you help me out
here?

Thanks

Well one side of the rotary runs real hot. That is the spark plug side and 
the bottom right side. The  intake side runs cool so the engine tends to bend
when it heats up. The hot water from the hot side is routed to the cool
side to heat it up and reduce the bending. If hot water is removed from
the back of the engine there is less hot water going to the cool side to 
warm it up.
